The Windows Hosts file is a system file you can edit to map hostnames or servers to IP addresses. Most people won't ever need to edit this file, but sometimes certain apps and services require making some changes. This wikiHow teaches you how to open, edit, and save the Windows Hosts file.

Step 1 Press the Windows key on your keyboard.

  • You may have to click Yes on a security warning to open the app.

Step 5 Click the File menu and select Open.

  • When you add a line to the hosts file, you'll want to enter the IP address first, followed by the domain name you're mapping it to. Separate the two with a space or a tab, and keep each entry on its own line. [1] X Research source
  • Lines that begin with a hash symbol # are considered comments, which means they are not active. Instead of deleting a line, just add a hash symbol to the beginning. This way you can easily reactivate old entries if you accidentally disable something you needed.

Step 10 Click the File menu and select Save.

How to Add a Local DNS Lookup to Hosts File

Great for blocking or redirecting websites

Author avatar

When you type a website URL into the address bar of your browser, a request is sent to a type of internet server known as a domain name server . This server takes the URL you typed and then checks which specific IP addresses are listed for the actual servers that host the content you’re looking for.

The problem with this is that if something’s wrong with the name server, you’re not going to get access to the correct site. Even worse, if the name server has been hijacked, you might end up at a fake site! The good news is that you can manually specify the link between specific IP addresses and website addresses, simply by adding a local DNS lookup to your “hosts” file.

What Is The Hosts File?

The hosts file is simple to understand. It’s just a plain text file. Incidentally, this is why you should just edit the file with something like Notepad, which won’t try to change the format or add extra formatting to the file.

Inside the hosts file, you can add a list of IP addresses along with the web address that the IP address should point to. You can combine any IP address and web address, even if they don’t actually go together. You could make the actual IP address for Bing.com point to Google.com if you wanted to.

Windows will always check the hosts file first before sending a request to a name server. So if an address you type into your web browser is listed in the hosts file, you’ll be redirected to the IP address listed in the file.

What Is A Local DNS Lookup?

The process described in the previous paragraph is a local DNS lookup. Your computer looks up the IP address by itself, from your local disk, without needing to contact an external server. It’s that simple!

Why Add Local DNS Lookup To The Hosts File?

There are a few reasons you’d want to add a local DNS lookup to your hosts file. We’ve already mentioned a few reasons at the outset of the article, but people have found quite a few creative ways to use this simple feature.

One important reason to add entries to your hosts file is speed. It will always be faster to do a local lookup than going out to an external server. Especially if that server is unreliable. Putting your most important or most frequently used sites in the hosts file means you never have to worry about your DNS service causing access issues.

You can also use the hosts file to block sites that you never want that computer to access. All you have to do is put an IP address into the hosts file for that site which either doesn’t go anywhere or points to a benign IP address. Common redirections include 0.0.0.0 and 127.0.0.1, This is the so-called “loopback” address. Check out our YouTube video for more details on that.

If you have local devices such as routers, IP cameras, network-attached storage and so on, you can use your hosts file to give their IP addresses an easy to remember name.

Using Premade Hosts Files

If it sounds pretty tedious to add dozens or even hundreds of sites to your hosts file, then you aren’t alone! The good news is that there are plenty of places on the web where you can find pre-made lists that you can simply copy and paste into your own hosts file.

The main problem with this is that there could be malicious reroutes hidden in these lists. Which means you either need to verify each IP address by hand or make sure that you trust the source of the list.

Editing The Hosts File In Windows 10

Since the hosts file leaves some room for mischief, you can’t just open it and edit away. You’ll need administrator privileges on your computer in order to make changes. Before you make any changes to your hosts file, we strongly recommend you copy and paste it’s original contents into another text file just in case something goes wrong!

To modify your hosts file in Windows 10, follow these steps:

  • Open the Start Menu and type “Notepad”.

How to Add a Local DNS Lookup to Hosts File image 4

  • Once Notepad appears, right-click on it and select “Run as administrator”.

How to Add a Local DNS Lookup to Hosts File image 5

  • n Notepad, click Open and head to c:WindowsSystem32Driversetchosts and open it the hosts file. Remember to change the file type to “All Files”.

  • You should see this default hosts file from Microsoft.

  • Don’t worry about any of the text already in the document. You can just leave it as is and add your own entries at the bottom of the file. Any line that starts with a “#” symbol is treated as a comment and not used for name lookups.

Adding a local lookup to the list is super-easy. Just write down the IP address of the site, followed by a space and then the website’s address.

Remember to save what you’ve added when closing the file. That’s all you have to do! Now your computer will skip over the whole DNS lookup process when accessing the sites you’ve specified.

How To Find A Website’s IP Address

What if you don’t know the IP address of a site you want to add to your hosts file? It’s actually pretty easy to find a site’s IP address using the Command Prompt in Windows 10. Here’s how:

  • Open the Start Menu and type “cmd”.
  • After the Command Prompt opens, type “tracert” followed by a space and the site you want to check. In this example, it’s “google.com”. Then press the Enter key on your keyboard.

  • Here you’ll see the IP address of the site.You can now use this address in your hosts file.

The Hosts With The Most

Who would think that such a small text file hidden deep in the Windows folder could turn out to be so useful? Now you’re a proper local lookup guru, taking control of how your computer accesses websites.

How To Edit the Hosts File in Windows 10

Little figures in front of a computer screen

The Domain Name System (DNS) is the key to locating a website on the Internet. With so much at stake, making changes to your DNS records can be a nerve-wracking experience.

Fortunately, there is a way to test DNS-related changes without editing your live records. By modifying your local hosts file, you can preview how your domains will function on a new server without putting your live site at risk.

In this post, we’ll explore what hosts files are and share some reasons why you may want to modify them. We’ll then show you how to edit hosts files on Windows 10. Let’s get started!

An Introduction to the Hosts File

A hosts file  is a local plain text file that maps your server or hostnames to Internet Protocol (IP) addresses . Every time Windows 10 connects over a network using a hostname, it’ll refer to the hosts file. If Windows finds an entry in this file, then it’ll contact the specified server.

If it doesn’t find a relevant hostname, Windows 10 will resolve the hostname using a Domain Name Service (DNS) . This is the process used to obtain the server IP address behind a domain name.

Each hosts file entry has its own line, with the numerical IP address, a space or a tab character, and finally the hostname or domain. Let’s look at an example of a hosts file entry:

120.0.0.0 example.com #Example

In the above example, the first section denotes the IP address where this request will be redirected to (120.0.0.0). The second section designates the location that we want to redirect a request from (example.com). The final section specifies a comment for this entry. We‘re using a hashtag to tell Windows 10 to ignore the comment when reading the local hosts file.

After adding the domain information, your system will resolve to the IP address you specified. In the above example, we’re associating the domain name example.com with the IP address 120.0.0.0.

It’s worth noting that some software employs its own techniques to look up hostnames. This means there’s always a chance that it may ignore the hosts file completely.

What Happens When You Modify a Hosts File?

When you modify your hosts file, it causes your local machine to look directly at the IP address specified by you. For example, if you wanted to point mywebsite.com to the IP address 1.2.3.4.5, you’d add the following:

1.2.3.4.5 mywebsite.com

Now, every time you try to visit mywebsite.com, you’ll find yourself at 1.2.3.4.5 instead. By editing your hosts file, you can override the DNS for a domain on your specific machine only.

In this post, we’ll be focusing on opening your hosts file and adding individual entries. However, it is also possible to replace this file entirely. This can be an easy way to block malicious or spammy websites in bulk. There are even sites that have published ready-made lists of IP addresses  associated with advertisements, hijackers, page counters, and other unwanted connections.

You can download one of these pre-prepared lists and copy/paste its contents into your existing hosts file. Alternatively, you might replace your native hosts file with the newly-downloaded file. If you do opt for the latter, then we recommend keeping a copy of your original file, just in case you encounter any strange behavior with its replacement.

Why You May Want To Modify the Windows 10 Hosts File

You can use your hosts file to test DNS-related changes without having to alter your DNS records. For example, imagine you’ve migrated to a new server. Before updating your DNS settings, it’s a good idea to verify how your domains will look and function on this new server.

However, if you enter your current domain name, then it’ll resolve to your old server. In this scenario, you can modify your hosts file to point the domain to the new server’s IP.

This file can also help test how your website looks on a different server when your DNS hasn’t propagated yet . At Kinsta we provide a temporary URL (sitename.kinsta.cloud), but this cannot mimic everything. For example, by default, a CDN won’t work on a temporary URL.

You can also use the hosts file to block certain websites. This can be useful for employers who want to ensure that their staff isn’t wasting time on unauthorized sites such as Facebook, Twitter, or YouTube.

While there are fewer technical ways to block access to unauthorized websites, many of these methods are relatively easy to reverse. For example, a tech-savvy child may have little problems bypassing parental controls, but modifying the hosts file requires a higher level of technical knowledge.

You might take this a step further and block all websites that serve up advertisements. If you map the addresses of all the major ad providers to an unused internal IP address, then Windows 10 will be unable to resolve these addresses. You can then enjoy the web, advertisement-free.

Finally, some malicious third parties may set up redirects by altering your hosts file. This is known as a hosts file hijack. If you’re encountering strange redirects, then it may be worth checking your hosts file for suspicious entries.

How To Make Firefox Honor the Windows 10 Hosts File

If you’re using Firefox for Windows, then Mozilla’s browser resolves IP addresses slightly differently compared to the other major browsers. By default, Firefox uses DNS-over-HTTPS (DoH).

This is a protocol for performing remote DNS resolution via HTTPS. With this setting enabled, Firefox will use the DOH server as the primary name resolver, rather than checking your local hosts file or DNS resolver.

As a result, the website displayed will always point to the IP address that the Internet deems authoritative for that domain. Even if you edit your hosts file, your changes won’t have any effect if the DoH server returns a working IP address.

There are plenty of great web browsers that are compatible with Windows 10 and that honor the hosts file out-of-the-box. However, if you want to stick with Mozilla Firefox, you can always disable DoH.

To start, select the Menu  button in the Mozilla Firefox browser and go to Settings .

Select the Menu button in the Mozilla Firefox browser and go to Settings.

In the subsequent tab, make sure General is selected. Then, scroll to the Network Settings  section and click on Settings .

Find network settings in Firefox

In the popup that appears, scroll to Enable DNS over HTTPS . Then, uncheck the accompanying box.

Scroll to Enable DNS over HTTPS

To save your changes, click on OK  and then exit this window. From this point onwards, Firefox will honor any custom addresses that you add to your Windows 10 hosts file.

How To Edit Your Windows 10 Hosts File (In 3 Steps)

There are many reasons why you might need to edit this important file. Regardless of whether you want to block advertising networks, verify a new domain, or perform other DNS-related tests, the process will be exactly the same.

Let’s look at how to add custom addresses to the Windows 10 hosts file.

1. Find Your IP Address

Often, you’ll want to change how Windows 10 resolves the IP address of a site that you own. To make this modification, you’ll need to know your website’s IP address.

If you’re a Kinsta customer, you can retrieve this information easily using the MyKinsta dashboard .

The MyKinsta dashboard

Find the domain that you want to work with and click on it. On the next screen, you’ll find some information about this domain, including your IP address.

Click on the

Alternatively, you might want to modify how Windows 10 resolves a third-party IP address. You can retrieve any website’s IP address using tracert.

Tracert is typically used as a network diagnostic tool to help resolve network connectivity issues. However, you can also use it to trace the paths a data packet takes from its source to its destination, which will reveal the IP address of the destination website.

To launch tracert, click on the Start  icon, then type command prompt  into the search bar.

Type command prompt into the search bar

When the command prompt icon appears, give it a click. In the subsequent window, type tracert  followed by the URL of the website in question, for example:

tracert website.com

Next, press the Enter  key on your keyboard. The command prompt will then display the IP address of website.com in a bracket alongside the URL.

2. Run Notepad as an Administrator

In Windows XP and earlier, editing your hosts file was relatively straightforward. You could simply add an exception to your antivirus, open the hosts file in the Notepad application, and then make your changes.

However, Windows 10 added some security measures to prevent users from accidentally modifying this important file. This makes sense, as editing the hosts file could potentially make your favorite websites inaccessible. In the worst-case scenario, it might even make the Internet unusable on your machine.

In Windows 10, the hosts information is stored in a plain text file in the internal System32  folder. While you should have no problems opening this file, when you try to save your edits you might encounter the following error: “You don’t have permission to save in this location. Contact the administrator to obtain permission”.

If you want to save your changes, you’ll need administrator access. The quickest way to gain this is to use a text application that has elevated privileges. In this post, we’ll be using Notepad.

To start, press the Windows  key and type Notepad  into the search field.

Search for the Notepad app

Next, right-click on Notepad  and select Run as Administrator . Windows 10 will now ask whether you want to allow this application to make changes to your device. Select Yes .

Select Run as Administrator

This launches a privileged instance of the Notepad application. Note that you may be asked to enter an administrative password in order to re-authenticate yourself.

3. Make Your Changes

Once you have Notepad open in administrator mode, you’re ready to edit the hosts file. In the Notepad toolbar, select File > Open .

Select File and then Open in the Notepad toolbar

Then, navigate to C:WindowsSystem32driversetchosts . Alternatively, you can copy/paste this file path into the address bar and then press Enter .

If you don’t see the hosts file in your /etc  directory, you may need to change the file filter type. In Notepad, open the File name  dropdown and choose All Files .

Open the File name dropdown and choose All Files

Once you have the hosts file in your sights, you’re ready to edit. If this is your first time opening this file, you’ll see some text describing the file’s purpose and how to make modifications, for example:

You can now add your custom IP address and hostname to the end of this file. If you’re adding multiple entries, remember to place each entry on a separate line. Once you’re happy with your changes, you can save and close the hosts file.

To make sure your computer recognizes your edits, it’s a good idea to flush the DNS cache. If you don’t currently have a command prompt window open, click on the Windows  button and search for command prompt . In the subsequent window, type the following:

To flush the DNS cache, press the Enter  key. Once this process is complete, Windows 10 should be using your new hosts file settings. Alternatively, restarting your computer should have the same effect.

How To Lock Your Hosts File on Windows 10

By default, you cannot edit the hosts file without administrator privileges. However, it isn’t impossible  to acquire these privileges, especially for tech-savvy individuals.

If you’re worried about unauthorized edits, you can add an extra layer of security to your hosts file. For example, you might be using the hosts file to prevent staff from accessing social media sites and you’re concerned about them bypassing your restrictions. You might also be worried about hosts file hijack attacks.

In these scenarios, you might want to consider locking your hosts file. While this security precaution isn’t bullet-proof, it will dissuade third parties from tampering with the file.

To lock your hosts file, navigate to C:WindowsSystem32driversetchosts . Then, right-click on the file and select Properties .

C:WindowsSystem32driversetchosts

In the Properties  window, mark the hosts file as Read-only . This will lock the file and prevent anyone from modifying it.

If you want to remove this lock at any point, simply navigate back to the Properties  window. You can then remove this Read-only  restriction.

How To Reset Your Windows 10 Hosts File

You can always remove individual entries from your hosts file. Simply open the file in Notepad and delete the line in question.

However, sometimes you may need to revert your hosts file to its original state. For example, you might have made multiple adjustments to your file and don’t particularly want to unpick each of these changes manually. You may also be encountering strange redirects, which suggests that your hosts file has become corrupted.

To reset your hosts file back to its original state, open your File Explorer. In the address bar, either type or copy/paste the following:

Then, press the Enter  key on your keyboard. At this point, we recommend renaming your original hosts file. This file will then serve as a backup, just in case you encounter any issues with your new hosts file.You may be required to take ownership of this file first, depending on how privileges are configured on your computer.

The next step is creating a new default hosts file. To achieve this, create a text file in the %WinDir%system32driversetc  directory, and name this file hosts .

You can now copy/paste the text from Windows’ default hosts file , which is provided by Microsoft:

Save this file. As always, you may need to reset your computer or flush your DNS cache in order for these changes to take effect.

Making changes to your DNS records can feel like a stressful endeavor. However, as we discussed in this article, you can safely test your local hosts file without putting your live records at risk. In Windows 10, you can do this by finding your IP address, running Notepad as an administrator, then making your changes.

How to Edit the Hosts File in Windows 10 [GUIDE]

How to Edit the Hosts File in Windows 10:  A ‘hosts’ file is a plain text file, which maps hostnames to IP addresses. A host file helps in addressing network nodes in a computer network. A hostname is a human-friendly name or label assigned to a device (a host) on a network and is used to distinguish one device from another on a specific network or over the internet. To locate a host in an IP network, we need its IP address. A hosts file serves by matching the host label to its actual IP address.

Want to Edit the Hosts File in Windows 10? Here is how to do it!

Table of Contents

Why is hosts file needed in your computer?

The www.google.com we use, for instance, is a hostname that we use to access the site. But in a network, sites are located using numerical addresses like 8.8.8.8 which are called IP addresses. Hostnames are used because it is not practically possible to remember the IP addresses of all the sites. So, whenever you type any hostname in your browser, the hosts file is first used to map it to its IP address and then the site is accessed. If this hostname does not have a mapping in the hosts file, your computer fetches its IP address from a DNS server (domain name server). Having a hosts file eases up the time used to query a DNS and receive its response every time a site is being accessed. Also, the mappings contained in the hosts file to override the data retrieved from a DNS server.

How to modify hosts file for your own use?

Editing a hosts file is possible and you might need to do it for a variety of reasons.

  • You can create website shortcuts by adding a required entry in the hosts file that maps the website IP address to a hostname of your own choice.
  • You can block any website or ads by mapping their hostname to the IP address of your own computer which is 127.0.0.1, also called loopback IP address.

How to Edit the Hosts File in Windows 10

Make sure to  create a restore point  just in case something goes wrong.

The hosts file is located at C:\Windows\system32\drivers\etc\hosts on your computer. Since it is a plain text file, it can be opened and edited in notepad . So without wasting any time let’s see How to Edit the Hosts File in Windows 10 with the help of the below-listed tutorial.

  • The hosts file from Windows converts the hostnames into numeric protocol addresses (IP address).
  • That is why editing the hosts file will help you override the DNS settings for a domain or a PC.
  • It’s very easy to do so by using Notepad but we also explain how to pin the shortcut for quick access.

Windows 10 and 11 hosts file editing

The computer’s hosts file is a Windows file that translates hostnames to IP addresses .

Precisely, it serves the function of converting the hostnames into numeric protocol addresses (IP address), that will locate a host in an IP network. The hosts file has the form of a plain text file.

Before the development of domain name systems (DNS), hosts files were the only solution for the computers to map hostnames to IP addresses.

After this process was automated through a DNS, the purpose of hosts file became a bit useless.

Most users of computers do not know that a file called hosts.txt exists. Still, in modern operating systems, his function can be handy.

The hosts file remains an alternative name interpretation mechanism and takes priority over the configured DNS server.

Why would you need to modify the hosts file?

Usually, editing the hosts file is performed to override the DNS settings for a domain or a computer.

For example, when you want to block the access to a specific website, from your computer. Or when you transfer a website to a new host provider.

First, you need to move the files to the new server and then shift the domain to a new IP address.

Or maybe, when you do not have a configured DNS server and you need to translate an IP address to a computer name. It’s just easier to use a hostname, than a sequence of numbers (IP address).

Whatever the reason you may have, in this article, we will list the steps to edit the hosts file on Windows 10.

How can I edit the host file in Windows 10?

1. Edit the hosts file using Notepad

1. Click on the  Start button on the taskbar or press the Windows key on your keyboard.

2. Type notepad in the search box that opened.

3. R ight-click on the first result and select Run as administrator .

notepad run as administrator windows 10

4. When the Notepad app opens, s elect  File , from the menu, and then Open .

notepad open new

5. You will find the  hosts.txt  in the following location (You need to select  All files  from the drop-down menu, in order to see the hosts.txt file): C:\Windows\System32\Drivers\etc

notepad all files windows

6. S elect the file and hit  Open .

notepad open hosts file windows

7. Make the desired changes in the hosts file. Write just one entry per line.

For example, type the IP address, space (or tab), and then the domain or computer name that you want to use to get to the device/application/website.

After these, you can add also a comment (with a # hashtag sign in front).

hosts file edit notepad

8. After you finish, click again on   File   and   Save .

9. Close Notepad.

If you need to make changes to the hosts file on your Windows OS, you can easily do this through the built-in Notepad tool.

After opening the hosts file in Notepad, you can modify it to override the current DNS settings and set-up new ones.

To block your computer’s access to a specific website, you can use an invalid IP address (e.g. 10.10.10.00 or localhost: 127.0.0.1) followed by the domain name (e.g. windowsreport.com) and the comment (e.g. #block site).

2. Test the hosts file using Command Prompt

search for cmd windows 10

If you change your mind, just open the hosts file again and edit or delete the lines. We also have a guide on how to reset the hosts file back to default in Windows 10 .

3. Create a shortcut for the hosts file

pin notepad to start

  • Then, click Apply and OK to make the changes.

If you are a programmer that works on websites, you probably need to edit the hosts file again and again.

To make things simpler, you can make a shortcut in the Start Menu, which will open the hosts file into Notepad, with administrator rights.

Are there differences when you edit the hosts file in Windows 11?

Although it comes with a lot of new features and design, Windows 11 is not that different from Windows 10.

That means, in part, that all the solutions to edit the hosts file we’ve presented above can be applied seamlessly for the new OS as well.

notepad pinned windows

In fact, it will be a little more simple because, as you will probably notice, Notepad is already pinned to the Start menu.

One more thing that you have to know about host file is that this file can be infected with malware.

Through hosts file, viruses corrupt your system and redirect it to other malware-ridden websites.

So, if you are trying to cleanse your computer, it’s always a good idea to check the hosts.txt file.

You can always clear things out by using a third-party antivirus like ESET HOME Security Essential which is very reliable and will do the job perfectly.

That’s it! Now you know how you can edit the hosts file in Windows 10 and 11 and override the DNS settings for a domain or a computer.

What is the Hosts file in Windows? How to edit etc/hosts?

What is the Hosts file in Windows? How to edit etc/hosts?

The Hosts file, a.k.a etc/hosts has been around since 1984. Every operating system has one, including Windows. You may have encountered the term etc/hosts without knowing what it means, and why it is used. If you are a web developer, you surely know what this file is, and you want to find it quickly. In this guide, we explain what the Hosts file is, where it is located in Windows, what a host entry is, and how to edit the Hosts file without stumbling into permission errors. Let's get started:

Skip to chapter

What is the hosts file in windows, where is the hosts file located in windows, what is host entry in windows, what is 127.0.0.1, how to open and view the hosts (etc/hosts) file in windows, how to edit the hosts (etc/hosts) file in windows, why do people use the hosts file, i can't edit the hosts file in windows what do i do, how do you use the hosts file in windows.

The Hosts file (also referred to as etc/hosts ) is a text file used by Windows (and other operating systems) to map IP addresses to host names or domain names. This file acts as a local DNS service , for your local computer, and it overrides the mappings from the DNS server that your computer is connected to, through the network.

The etc/hosts file in Windows

The Hosts files (or etc/hosts ) is found in the following folder: "C:\Windows\System32\drivers\etc"

The location of the Hosts file, in Windows

It is a file with no file extension, that can be opened and viewed in any text editor, including Notepad .

The Hosts file stores host entries . They are standardized lines of text that use the following format: IPaddress Hostname Comment . The first part is the IP address to redirect to, the second part is the domain that you want to redirect, and the third is a comment. The comment is not mandatory only the first two parts are. You can separate the three components of a host entry with spaces or TABs (press the TAB key once or twice). For example, you can add a line that says: "127.0.0.1 www.google.com"

Editing the Hosts file in Notepad

Once you save the entry above, Windows redirects the domain www.google.com to your local computer, in all your apps and web browsers.

127.0.0.1 is a special purpose IP address that leads to the localhost, which is your computer. It is also called "loopback address," meaning an address that leads back to the computer using the address. Unlike standard IP addresses , the loopback address is not associated with any hardware, and it is not physically connected to a network. This address is used by apps and services that are installed on your computer, to communicate with the localhost, meaning your computer.

localhost redirect

Your computer also has a unique IP address, different from 127.0.0.1, associated with your network card, that is used to communicate with other devices and services over the network or the internet.

Most often, the localhost IP address is used when installing a web server on your computer, for web development, so that the web pages that are created can be run locally, and tested in a web browser, as if they were live on the internet.

To avoid conflicts in computer networks, the IP addresses used for network devices can be anything except 127.0.0.1. For example, if you manually try to modify the IP address of your network card, in Windows, you receive an error stating that: "IP addresses starting with 127 are not valid because they are reserved for loopback address. Please specify some other valid value between 1 and 223."

IP addresses starting with 127 are not valid

You can edit the Hosts file using any text editor. Let's use Notepad , for example. First, and most important, is that you open Notepad (or your favorite text editor) with administrator permissions. One way to do that is to search for the word "notepad" in Windows 10, right-click (or tap and hold) the Notepad search result, and then click or tap "Run as administrator." In the UAC prompt that is shown, press Yes .

Open Notepad as admin

Now you need to open the Hosts file. Click or tap File and then Open , or press CTRL+O on your keyboard.

Open a file in Notepad

Browse to "C:\Windows\System32\drivers\etc" or copy and paste the path in the address field of the Open window, and press Enter .

Open C:WindowsSystem32driversetchosts in Notepad

At first, "no items match your search" meaning that you do not see any files. That's because the Hosts file does not have a file extension, and Notepad is looking only for files with the ".txt" extension. Click or tap the drop-down list to the right of the File name field, and choose "All Files (*.*)."

See All Files with Notepad

Now you see all the files in the folder, including hosts . Select the file and press Open .

Open C:WindowsSystem32driversetchosts in Notepad

After you have opened the Hosts file, you can edit it, and add, change or remove entries, as you do in any other text file.

Remember that all the entries that you add must use this format: IP address Hostname . Add a line like "127.0.0.1 www.google.com" or "192.168.1.1 www.webapp.com"

Editing the Hosts file in Notepad

When you are done editing the Hosts file, you need to save your changes. If changes are made and not saved, notice that the tile of the Notepad window starts with a * sign. To save your changes, go to File and then Save or press CTRL+S on your keyboard.

Saving the Hosts file in Notepad

After you have saved your changes, they are applied immediately and override the mappings from the DNS server that your computer is connected to.

Most casual computer users are not going to use the Hosts file unless they want to pull a prank on someone and use it to block their access to Google, Facebook or some other site, and make them think that it is down, and no longer working. The people using the Hosts file most frequently are web developers who create websites and web apps, which must be tested locally, before publishing them on the internet.

Google.com blocked by the Hosts file

IT professionals also use the Hosts file to block access to specific sites and web resources, on the computers they are managing at work. For example, they can use it to block advertising in their business network, from specific ad networks.

Malware can also use the Hosts file to redirect your web traffic to remotely controlled servers and steal personal information or other data.

When editing and saving the Hosts file in Windows, you may receive an error message that states: "You don't have permissions to save to this location." This happens because you did not open Notepad or the text editor that you are using, with administrator permissions. Read the sections above and see how to start Notepad with administrator permissions.

Error message: You don't have permissions to save in this location

After you do that, you can edit the Hosts file without any errors and permission problems.

How to Edit the Hosts File in Windows 10

how to add ip in host file in windows 10

There’s an easy way and a hard way to edit the hosts file in Windows 10. In this article, we’ll show you both.

If you’re a regular groovyPost reader, you know that DNS translates domain names like groovyPost.com into IP addresses like 104.24.11.25. But did you know that there’s a file on your Windows 10 PC that can override that? It’s called your hosts file and it lets you map specific domain names to an IP address of your choosing. Your hosts file only affects your computer, so you can use it to create custom URLs for IP addresses on your network, or you can use it to redirect certain websites.

As you can imagine, editing the hosts file can easily break your internet if it’s modified incorrectly or maliciously. So, it’s not particularly easy for a normal user to edit. This is a good thing. But if you want to change your hosts file purposefully, here’s how.

Edit Your Windows 10 Hosts File as an Administrator

The hosts file is normally stored in a plain text file in the Windows System folder and can be modified for various use cases. One particular reason I edited the hosts file in the past was to block certain websites when I managed computers for a local high school. This was probably one of the best and easiest ways I could ensure students didn’t load any unauthorized websites such as Facebook or YouTube.

Editing your Windows hosts file doesn’t have to feel like going down a rabbit hole. In Windows XP and earlier versions, the process was quite easy. All you needed to do was add an exception to your antivirus, open the file in Notepad, make your changes, and then save it.

In Windows 10, if you try to edit your hosts file, you’ll probably be able to open it just fine, but when you go to save it, you’ll get an error:

no permission to edit hosts file error

Here’s how you can edit your hosts file without getting the “You don’t have permission to save in this location. Contact the administrator to obtain permission” error.

  • Click the Start menu or press the Windows key and start typing Notepad .

Run Notepad as administrator

  • Start with the target IP address, then a space, then the domain name. If you want to block a website, redirect it to 127.0.0.1.
  • Don’t put in the # if you want it to take effect.
  • Also, remember that www.youtube.com is different from youtube.com.

You may need to restart your computer for the new hosts file to take effect.

An Easier Way to Edit the Hosts File in Windows 10

If you found that process a bit cumbersome, there’s a third-party utility you can use to modify your hosts file. I found a good one called Hosts File Editor by Scott Lerch . Let’s take a look and see how it works.

Installing Hosts File Editor

Hosts File Editor features a clean, easy-to-use interface. To begin using the program, populate the table with IP Addresses, Host Names, and comments on the websites you want to manage. It’s not just limited to popular Internet websites. Even devices on your home network with an IP address can be managed, so your Xbox, iPad, web cameras, or routers are much easier to block access to if needed.

Hosts File Editor interface

When you are ready to block a website, check the box for the sites you want to prevent access to, click Save, and that’s it.

Making changes to hosts file

Another nice ease-of-use feature is the ability to right-click the Hosts File Editor in the Notification area, click Disable Hosts File, or make a quick edit. No need to go hunting or launch the command line anymore.

Hosts File Editor in notifications center

There are some other cool features included for power users and network administrators, such as:

  • Cut, copy, paste, duplicate, enable, disable, and move one or more entries at a time.
  • Filter and sort when there are a large number of host entries
  • Archive and restore various hosts file configurations when switching between environments
  • Automatically ping endpoints to check availability

So, there you have it, a quick and easy way to edit your Hosts File in Windows 10.

Followed all of your instructions for editing the HOSTS file. Even running notepad in administrator mode, I still get the “you do not have permissions . . .” message. Has Win 10 made changes subsequent to your posting?

Steve Krause

June 28, 2018 at 10:50 am

Hi Harry – Nope, process is still the same with the latest version of Windows 10.

Confirm you are Admin on the PC you’re trying to do this on. If you’re not an Admin, it won’t work. You can also try this: Click Start Button > Type: CMD > Right Click Command Prompt > Click Run as Administrator > goto c:\windows\system32\drivers\etc > type: notepad hosts

Make your changes, save and you should be golden.

Hello Andre, thank you so much for giving me this helping hand after hours and hours of searching.

Trying to set up a testing environment for a new website, I needed to add two local hosts in the hosts file. I ran into two problems. a) – The hosts file was not in drivers/etc/. FileFind did the job and found in some obscure location; maybe a backup inside windows. Opening the file there gave me the same screen as you show here, preventing me from editing. Not being a network ‘guru’, that looked like a lot of trouble. Never giving up. I have no choice. b)- once more looking in c:/windows/system32/drivers/ I was unable to find the directory /etc. Typed etc in de next step for opening a file. And that brought me to that invisible dir etc. And there was the hosts file too! After editing, I closed the file with just ‘save’, not ‘save as’. After that the hosts file was updated.

Blocking unwanted sites is a great possibility, it stopps certain websites from following a user browsing the net.

Happy with your help. Greeting from The Netherlands.

I have done as you told and I open as administrator and change the file but when I am saving it. It is saving in txt file and when I am forcing it to save as host it saying the file is read-only you can’t make changes.

Wonderful post but I was wondering if you could write a litte more on this topic? I’d be very thankful if you could elaborate a little bit more. Bless you!

September 19, 2019 at 8:38 am

You people that are saying there’s nothing there well notepad no matter how you open it is looking for text while so you have to change it to all files to see anything there. I also cannot use the go to command in the CMD program as it will not go past the system32 folder. I have tried everything I can with administrator privileges and cannot change this damn file even in safe mode with the internet turned off. I have tried security settings for the file and it does not work. You’ll see a million bits of advice saying the same thing on every website but this file is getting really stupidly hard 2 Chainz even though most of the time it is never used.

What to Know

  • Open Notepad or another text editor > select File > Open > open Host file.
  • Next, select Text Documents (*txt) and change it to All Files > double-click hosts .
  • Make changes and save.

Here's how to edit the Windows HOSTS file, which is necessary to make custom domain redirects, block websites, or remove malicious entries set by malware. Instructions apply to Windows 10, 8, 7, and XP.

How to Edit the Windows HOSTS File

In Windows 10, 8, and 7, you can't save edits to the HOSTS file unless you open it directly from Notepad or another text editor. To do so:

Open Notepad or another text editor like Notepad++.

In the text editor, select File > Open and open the HOST file location at C:\Windows\ System32 \drivers\etc\ .

Select Text Documents (*txt) in the bottom-right of the Open window and change it to All Files .

This step is required because the HOSTS file doesn't have the .TXT file extension .

When files appear in the folder, double click hosts to open it.

Edit the HOSTS file and save your changes.

What If I Can't Save the HOSTS File?

In some versions of Windows, you don't have permission to save directly to the   \etc\  folder. If this is the case, you might see an error like this one when you try to save:

Instead, you must save the file elsewhere like the Documents or Desktop folder. After saving, go to that folder, copy the HOSTS file, and paste it directly into the location where the HOSTS file should be ( C:\Windows\System32\drivers\etc\ ). You'll be prompted with permission validation and will have to confirm overwriting the file.

If you still have trouble saving the modified HOSTS file, check the file's attributes to see if it's been marked read-only . Right-click the file and select Properties to see the attributes.

Another option is to open your text editor program as an administrator so that the permissions are already applied to the editor. Then, saving the HOSTS file over the original can be performed without having to verify your admin credentials.

If you still can't save to the HOSTS file location, you probably don't have the correct permissions to be editing files in that folder. You should be logged in under an account that has administrative rights over the HOSTS file, which you can check by right-clicking the file and going to the Security  tab.

What Is the HOSTS File Used For?

The HOSTS file is the virtual equivalent of a phone company's directory assistance. Where directory assistance matches a person's name to a phone number, the HOSTS file maps domain names to IP addresses.

Entries in the HOSTS file override DNS entries maintained by the ISP . While this hierarchy might come in handy for regular use, like to block ads or certain malicious IP addresses, its functions also make this file a common target of malware.

By modifying it, malware can block access to antivirus updates or force you to a malicious website. Thus, it's a good idea to check the HOSTS file periodically or at least know how to remove false entries.

A much easier way to block certain domains from your computer is to use a custom DNS service that supports content filtering or blocklists.

How can I specify IP and ports for a hostname in the Windows hosts file?

I want to specify host names with two different ports in the Windows hosts file.

Is there a way to do it? Or is it not allowed by Windows itself?

I have been wasting my time searching for the solution for the last 8 hours.

Is it possible to specify ports in the host file, hosts ? E.g.: 127.0.0.1:80 and 127.0.0.1:9211

Peter Mortensen's user avatar

  • 2 The HOSTS file only associates names with IP addresses, not IPs+port(s). Do check superuser.com, however, by describing more of the specifics of what you are trying to do (is this for a web server etc. etc.) as there are many ways to achieve this type of mapping, but always depending on specifics at hand. –  mjv Commented Feb 21, 2010 at 18:44
  • You need NGNIX or Apache HTTP server as a proxy server for forwarding http requests to appropriate application -> which listens particular port –  Musa Commented Feb 8, 2018 at 18:08

Simply use IP addresses without ports. Example:

Then, to access 192.168.2.50:5555 from your browser (or other program):

The hosts file can be found at:

Linux /etc/hosts

Windows : C:\Windows\System32\drivers\etc\hosts

  • It will be helpful to add both path and the name of the file to be edited. –  nyedidikeke Commented Sep 15, 2016 at 10:21
  • 1 Can you possibly update with the reason for NOT specifying the port number when editing the file at C:\Windows\System32\drivers\etc\hosts ? –  nyedidikeke Commented Sep 15, 2016 at 19:57
  • 1 That's covered in the other answers. –  Scott - Слава Україні Commented Sep 15, 2016 at 21:35

You cannot associate a port number with a hostname mapped to an IP in the hosts file. You can achieve this with Fiddler though using FiddlerScript: 

Community's user avatar

  • 8 Nice suggestion for tech users. Just to clarify, 1) First install Fiddler 2) Then open it and go to Rules Menu and pick Customize Rules option ( or press Ctrl + R on windows ). This will open a JS file in notepad. 3) Find static function OnBeforeRequest and paste the script suggested by @John inside its body. Also HostNameIs will not work, it should be HostnameIs. Hope this helps. –  Riz Commented Aug 13, 2013 at 7:40
  • Are you aware of any open source alternative (james, owasp zap, or other) which can be used to the same effect? –  Marc.2377 Commented Dec 21, 2018 at 18:36
  • The hosts file is for resolving hostnames to IP addresses only
  • If you do not specify a port as part of a URL, e.g. <protocol>://<hostname>[:<port>][/path] , your browser will use the default port for the protocol: HTTP/80, HTTPS/443, FTP/21

Example Problem Scenario

  • Applications typically set their servers to the same default IP address 127.0.0.1 (aka localhost , defined in the hosts file) .
  • "if" you could change the servers IP address to another in the loopback reserved address space 127.0.0.0/8 , then you probably wouldn't be attempting to set ports in the hosts file

Possible Solution

You can work around this using Windows' built-in networking tool netsh as a port proxy.

  • Start your app's HTTP server on a custom port: localhost:8081
  • Example: 127.65.43.21 example.app
  • I suggested 127.65.43.21 but any free address in the subnet 127.0.0.0/8 can be used
  • Verify that 127.65.43.21:80 isn't already in use by another service. If it is, use a different IP. Check using: netstat -a -n -p TCP | FINDSTR "LISTENING"
  • Add the following network configuration, using netsh :
  • Try to access the server at http://example.app
  • These commands/file modifications need to be executed with Admin rights
  • netsh portproxy needs IPv6 libraries , even just to use v4tov4 . Typically, these will be installed by default, otherwise, install them with netsh interface ipv6 install

You can see the entry you have added with the command:

You can remove the entry with the following command:

How to edit Hosts File on Windows 10

Windows 10 makes it harder to edit Hosts file by making it read-only. We can edit Hosts file easily using Notepad or even from command-line or remotely. We will discuss all these methods in this article, so stay tuned.

What is a Hosts file?

The hosts file is essentially the first place your computer looks for an IP address when you are browsing through the internet. It is a file found on your computer that contains the name of a website and its corresponding IP address.

When you type in “itechtics.com” on your web browser, your computer goes to find the corresponding IP address in the hosts file. If the entry is not found there, it then goes to the Domain Name Server (DNS) associated with your computer.

Let us show you how you can modify the hosts file on your computer and any other computer on your network remotely.

Why you might need to modify the hosts file

This technique is often used by individuals to block certain websites on computers. However, it is not the most optimized way to do so, as the users can change or remove the entry in the hosts file to revert their networking settings.

How to edit hosts file on a local computer

Let us show you how you can modify the hosts file successfully, without any errors, that is located at the following location:

hosts changes

You can now check that the URL you have entered in the hosts file will now redirect to the corresponding IP. Since we entered 0.0.0.0 in our example, the website www.itechtics.com is no longer accessible.

How to edit hosts file using the Command-line

Alternatively, you can also use the Command Prompt to edit the hosts file in a few easy steps. However, the Command Prompt must be opened as an administrator .

How to edit hosts file on a remote computer

This part involves some additional steps. However, it is still beneficial and better than going to each computer physically and altering the hosts file. Nonetheless, you will need to perform a small task on the remote computer(s) that will need to be done through physical presence.

The following is valid for computers that are on the same network/domain as the source computer.

This will add a new DWORD to the Windows Registry that will allow you to access the computer remotely through PsExec.

Closing words

Although the hosts file is of significance to the Windows system, it does not affect it in any way if you decide to delete the file voluntarily or involuntarily. Unless you have made certain changes to the file, nothing drastic happens if you remove the entire file. It can always be replaced with a blank file with the name “hosts”.

Hosts File Editor utility

  • 6 contributors

Windows includes a local "Hosts" file that contains domain names and matching IP addresses, acting as a map to identify and locate hosts on IP networks. Every time you visit a website, your computer will check the hosts file first to see which IP address it connects to. If the information is not there, your internet service provider will look into the Domain Name Server (DNS) for the resources to load the site. The Hosts File Editor provides a convenient way to edit the hosts file. This can be useful for scenarios like migrating a website to a new hosting provider or domain name, which may take a 24-48 hour period of downtime. Creating a custom IP address to associate with your domain using the hosts file can enable you to see how it will look on the new server.

Adding a new entry

Ensure that the Hosts File Editor is set to On in the PowerToys Settings.

To add a new entry using the Hosts File Editor:

  • Select New entry
  • Enter the IP address
  • Enter the Host name
  • Enter any comments that may be helpful in identifying the purpose of the entry
  • Turn on the Active toggle and select Add

Filtering host file entries

To filter host file entries, select the filter icon and enter data in either the Address, Hosts, or Comment field to narrow the scope of results.

Back up Hosts file

Hosts File Editor creates a backup of the hosts file before editing session. The backup files are located near the hosts file in %SystemRoot%\System32\drivers\etc named hosts_PowerToysBackup_YYYYMMDDHHMMSS .

From the Settings menu, the following options can be configured:

Setting Description
Open as administrator Open as administrator to be able edit the hosts file. If disabled, the editor is run in read-only mode. Hosts File Editor is started as administrator by default.
Show a warning at startup Warns that editing hosts can change DNS names resolution. Enabled by default.
Additional lines position Default value is . If is selected, the file header is moved below hosts settings to the bottom.
Consider loopback addresses as duplicates Loopback addresses (like 127.0.0.1 and ::1) are considered as duplicates.

Troubleshooting

A "Failed to save hosts file" message appears if a change is made without administrator permissions:

PowerToys Hosts File Editor: Failed to save hosts file

Select Open as administrator in settings to fix the error.

Easily Edit the Hosts File in Windows 10

Most operating systems, including Microsoft Windows versions, use the hosts file to translate computer names. Also known as “host names” to numerical IP addresses, the hosts file is similar to using a phone book to find the matching phone number of a specific person’s name. Note : This article was written at the time when Windows 10 was at Technical Preview build phase. While Domain Name System – or DNS – is mostly used for this function (being a centralized and half-automatically managed name resolution system), the HOSTS file can be used as a local name resolution mechanism, and when used in conjunction with other name resolution mechanisms such as DNS, the HOSTS file takes precedence over them. This is why many users still edit the HOSTS file and add names and IP addresses of servers, websites and other computers they frequently access to it.

Location of the Hosts File

In Microsoft operating systems, the HOSTS file is located in the following location: C:\Windows\System32\Drivers\etc Note: We also have tutorial articles on how to  edit a hosts file in Windows 8 ,  edit a hosts file in Windows 7 and on a mobile device running Windows RT .

How the Hosts File Works

The HOSTS file is a text file, one that does not have a file extension. It contains lines of text that are made of IP addresses followed by one or more host names or fully qualified domain names ( FQDN s). Each field is separated by white space (blanks or tabulation characters). For example, if you wanted to use the HOSTS file to translate a host name of a computer called “printserver” into the IP address of 192.168.0.1, you would add this line:

You can add more than one host name to the same IP address. For example, if the computer called “printserver” also acts as a scanner called “scanserver”, you could use this line:

A Step-by-Step Guide to Editing the Hosts File in Windows 10

  • TroubleShooting

In this article, we will explore the process of editing the hosts file in Windows 10. The hosts file is a text file that maps IP addresses to hostnames. By modifying this file, you can control how your computer resolves domain names, which can be useful for various purposes, including blocking unwanted websites and redirecting traffic.

Understanding the Basics of the Hosts File

The hosts file is an important part of the networking infrastructure in Windows 10. It acts as a local DNS resolver, allowing you to specify custom mappings for domain names. When your computer tries to access a website, it first checks the hosts file to see if there is a custom mapping for that domain. If a match is found, your computer will use the IP address specified in the hosts file instead of querying a DNS server.

The hosts file is a plain text file located in the system directory of your computer. By default, it does not have a file extension. You can open and edit the hosts file using a text editor such as Notepad. However, administrative privileges are required to make changes to the hosts file.

Each line in the hosts file consists of an IP address followed by one or more domain names. The IP address is separated from the domain names by one or more spaces or tabs. You can add comments to the hosts file by starting a line with the “#” character. These comments are ignored by the system and can be used to provide additional information or explanations.

Exploring the Purpose of the Hosts File

The hosts file serves several purposes in the networking ecosystem. One of its primary uses is to override the default DNS resolution process. When you enter a domain name in your web browser, the browser sends a request to a DNS server to obtain the IP address associated with that domain. However, by modifying the hosts file, you can bypass this process and directly specify the IP address to be used for a particular domain.

This can be particularly useful in situations where you want to access a website using a different IP address than the one specified by the DNS server. For example, if a website is hosted on multiple servers and you want to test its performance on a specific server, you can add an entry in the hosts file to map the domain name to the IP address of that server.

In addition to overriding DNS resolution, the hosts file can also be used to block access to specific websites . By redirecting the domain names of these websites to the localhost IP address (127.0.0.1), you effectively prevent your computer from connecting to them. This can be helpful in avoiding distractions or protecting your system from potentially harmful or malicious websites.

Benefits of Modifying the Hosts File in Windows 10

Modifying the hosts file can be beneficial for a variety of reasons. One of the main advantages is the ability to block access to specific websites. This can be particularly useful for parents who want to restrict their children’s access to certain websites or for individuals who are trying to limit their own browsing habits.

Another benefit of modifying the hosts file is the ability to create custom local domain names for testing purposes. This can be especially valuable for web developers and network administrators who need to test websites or applications locally before deploying them to a production environment. By mapping a custom domain name to the local IP address of their development machine, they can easily access and test their projects without the need for a public domain name or DNS configuration.

Furthermore, the hosts file can also be used to redirect domain names to alternative IP addresses. This can be helpful in scenarios where a website or service is temporarily unavailable or experiencing issues. By redirecting the domain name to a different IP address, users can still access the website or service without relying on the default DNS resolution process.

It is important to note that modifying the hosts file requires careful consideration and should be done with caution. Incorrect entries or misconfigurations can lead to unexpected behavior and may cause connectivity issues. Therefore, it is recommended to make a backup of the original hosts file before making any changes and to consult relevant documentation or seek professional advice if needed.

Configuring Firefox to Respect the Windows 10 Hosts File

If you’re using Firefox as your web browser, there is a specific configuration you need to make to ensure it respects the changes made in the hosts file. By default, Firefox uses its own DNS resolver , which can bypass the hosts file. This can be problematic if you rely on the hosts file to block certain websites or redirect them to different IP addresses. Fortunately, there is a simple solution to this issue.

To configure Firefox to respect the Windows 10 hosts file, follow these steps:

  • In the Firefox address bar, type “about:config” and press Enter. This will take you to Firefox’s advanced configuration settings.
  • Click on the “I accept the risk!” button to proceed. This is a necessary step to access the advanced settings.
  • Search for the “network.dns.offline-localhost” preference. This preference determines whether Firefox should use the hosts file for localhost addresses when offline.
  • Double-click on the preference to set the value to “true”. This will enable Firefox to respect the Windows 10 hosts file.

Once you have made these changes, Firefox will respect the Windows 10 hosts file and use the custom mappings specified in it. This means that any changes you make to the hosts file will be reflected in Firefox’s DNS resolution. Whether you’re blocking certain websites, redirecting them to different IP addresses, or simply managing your local development environment, Firefox will now adhere to the rules defined in the hosts file.

It’s worth noting that the hosts file is a powerful tool for managing DNS resolution on your computer. It allows you to override the default DNS settings and specify custom mappings between domain names and IP addresses. This can be useful for a variety of purposes, such as blocking malicious websites, redirecting traffic to local servers, or testing website changes before making them live.

By configuring Firefox to respect the Windows 10 hosts file, you can ensure that your browsing experience aligns with the rules and mappings defined in the hosts file. This can provide an added layer of security and control over your online activities. So, if you’re using Firefox and rely on the hosts file for DNS resolution, don’t forget to make this important configuration change.

Simple Steps to Edit Your Windows 10 Hosts File

Step 1: locating your ip address.

Before you can edit the hosts file, you need to know your IP address. To find out your IP address in Windows 10, follow these steps:

  • Open the Command Prompt by pressing Win + R, typing “cmd” and pressing Enter.
  • In the Command Prompt window, type “ipconfig” and press Enter.
  • Look for the “IPv4 Address” or “IPv6 Address” under the network adapter you are currently connected to.

Make a note of your IP address, as you will need it later when editing the hosts file.

Step 2: Running Notepad as an Administrator

Editing the hosts file requires administrative privileges. To run Notepad as an administrator, follow these steps:

  • Open the Start menu, search for “Notepad”, and right-click on the Notepad application.
  • Select “Run as administrator” from the context menu.

By running Notepad as an administrator, you ensure that you have the necessary permissions to modify system files like the hosts file.

Step 3: Modifying Your Hosts File

Now that you have opened the hosts file in Notepad with administrative privileges, you can proceed with making your desired changes. The hosts file is located in the following directory: C:\Windows\System32\drivers\etc\hosts

Each line in the hosts file consists of an IP address followed by one or more hostnames separated by spaces or tabs. To create a custom mapping, simply add a new line following this format:

[IP address] [hostname1] [hostname2] …

Once you have made your changes, save the hosts file and exit Notepad.

Securing Your Hosts File in Windows 10

After modifying the hosts file, it is important to take steps to secure it. Since the hosts file has system-wide effects, it’s essential to prevent unauthorized changes that could compromise your system’s stability or security.

One way to secure the hosts file is by setting its permissions to read-only. To do this, follow these steps:

  • Locate the hosts file in the C:\Windows\System32\drivers\etc\ directory.
  • Right-click on the hosts file and select “Properties” from the context menu.
  • In the Properties window, go to the “Security” tab.
  • Click on the “Edit” button to change the permissions.
  • Select “Users” from the list of Group or user names.
  • Check the “Read & Execute” and “Read” permissions in the “Allow” column.
  • Click on “Apply” and then “OK” to save the changes.

By setting the hosts file to read-only, you can prevent accidental or unauthorized modifications.

Restoring Your Windows 10 Hosts File to Default

If you ever need to restore your hosts file to its default state, you can do so by following these steps:

  • Open Notepad as an administrator.
  • Click on “File” in the Notepad menu, then select “Open”.
  • Navigate to the C:\Windows\System32\drivers\etc\ directory.
  • Change the file type filter to “All Files”.
  • Select “hosts” from the list of files, then click on “Open”.
  • Delete all the existing lines in the hosts file.
  • Copy and paste the following line into the empty hosts file:

127.0.0.1 localhost

Save the hosts file and exit Notepad. Your hosts file will now be restored to its default state.

Recap and Conclusion

In this step-by-step guide, we have explored the process of editing the hosts file in Windows 10. We have discussed the purpose of the hosts file, its benefits, and various steps to edit and secure the file. By following these instructions, you can take control of how your computer resolves domain names and ensure a safer and more customized browsing experience.

Remember to use caution when editing the hosts file and make sure to make backups before making any changes. With these guidelines, you can confidently navigate the process of modifying the hosts file in Windows 10.

A better way to add and remove Windows hosts file entries

In this article I present a couple of simple PowerShell scripts which will modify the hosts file on one (or more) Windows machines, so that you can route traffic destined for certain domains to specific IP addresses with minimal fuss. The scripts do this by adding (or removing) entries to (or from) the hosts file and they do this idempotently [1] , so you don't need to write any checks when adding or removing. In other words, when you add a host to the hosts file, it won't add it if it's already there.

It could be argued that modifying the hosts file is not really how you should be doing things in a production environment, but it's easy to imagine various scenarios in which it could be useful.

I'll also explain a few useful features of PowerShell scripts, such as the proper way to add support for the -WhatIf parameter.

Additionally, there's an extra script which enables you to copy your modified hosts file to multiple machines. This needs to be used with extreme caution (although it does make a backup of the remote hosts file), but is useful if you are trying to get precisely the same hosts file onto several machines in one step.

All of the scripts are in GitHub at:

https://github.com/TomChantler/EditHosts

If you need to override DNS settings and route traffic for certain domains to specific IP addresses of your choosing then, if you don't want to mess around with DNS servers and/or proxies, the easiest way is to modify your hosts file. But what if you're dealing with a cluster of machines? What if you're not sure if you've already added some of the hosts entries? What if you need a script to automate the process? Don't worry, I've got you covered.

Why would you do that?

A short while ago, I had a problem and I needed to roll out a quick fix in order to change the routing of traffic to certain domains, for reasons which we don't need to go into now [2] . I needed to do this on several machines in a production environment and I wanted to make it as safe as possible. Bear in mind that I've tidied up the scripts quite a lot since I ran them in real life. Scary stuff, eh?

There are other, less exhilarating reasons that you might want to do this, particularly when you are developing software.

There are three scripts:

AddToHosts.ps1

RemoveFromHosts.ps1

UpdateMultipleHostsFiles.ps1

They do exactly what you might imagine.

This script adds entries to your local hosts file idempotently and can take three parameters:

  • -Hostname (this is the hostname you want to add)
  • -DesiredIP (this is the IP address you want to associate with that hostname)
  • -CheckHostnameOnly (if this is false (which it is by default) then it checks the combination of hostname and IP address is unique. If it's true, then you can only have one entry per hostname (which is probably more sensible). However, setting it to false allows you to add IPv4 and IPv6 entries, but it also allows you to cause yourself difficulties. Approach with caution)

Example usage:

You can see the idempotent nature of the script in this screenshot.

Add entries to hosts file

This script removes entries from your local hosts files and takes one parameter:

  • -Hostname (this is the hostname you want to remove)

It removes all entries for a single domain. So if you have both IPv4 and IPv6 entries, or if you have made a mistake and added multiple entries for a single domain, it will remove all of them.

Remove entries from hosts file

This script copies your local hosts file to one or more remote machines (it makes a backup called hosts.bak in the same directory before doing so) and can take two parameters:

  • -ServerList (this is the list of remote servers)
  • -Timeout (this is how many seconds it should try to copy each hosts file before timing out. Default value is 5 seconds).

As you can see from the screenshot, you get a nice colour-coded error message for any remote machines it can't reach and it will try every machine in the list once.

Update multiple hosts files

A note about -WhatIf

In PowerShell there are certain conventions and one of these is the -WhatIf parameter. In brief, adding -WhatIf to a cmdlet which supports it will show you what the cmdlet is going to do, without actually doing anything. Think of it like a trial run.

To add -WhatIf support to your own cmdlet, add the following to the top of your script:

[CmdletBinding(SupportsShouldProcess=$true)]

If you've written a proper function (and not just a simple script), add it just after the definition, but before the parameters, like this:

There are a couple of ways to check if you're executing in -Whatif mode.

The most common way is like this:

Which gives the following output (which is somewhat fixed, as you will see). Note that it doesn't execute the code contained in the curly braces:

You can also check it like this ( $WhatIfPreference is set automatically):

Or even by doing this (which is a bit strange, hence why I did it in this script):

Checking in this way might be handy as you could optionally leave out the else clause or tailor your output (even omitting it completely if desired).

The really clever thing about -WhatIf The really clever thing about the -WhatIf parameter is that, if you call any cmdlets in your script which also support the -WhatIf parameter, then you don't need to check for it explicitly, as long as you remembered to add [CmdletBinding(SupportsShouldProcess=$true)] to the top of your script.

There are various reasons (not all of them nefarious) why you might want to edit your Windows hosts file to change the routing of certain domains. These scripts are a safe, easy way to do that, especially in the case where you need to update multiple machines at the same time. A little while ago, I used a somewhat less-sophisticated version of these scripts in real life to fix a major problem. I hope they can help you in a somewhat less stressful scenario.

Follow me on Twitter for more frequent updates. Follow @TomChantler

In a computing context, an idempotent operation can be performed multiple times and always achieve the same result. So in our example of adding an entry to the hosts file, we could perhaps better call it "Ensure Entry Occurs Once In Hosts File" as that's what it's really doing. This is the sort of thing people get asked in job interviews, although it's one thing to know what it means and another to know when it's a good idea to do it. ↩︎

How To Modify The Hosts File On Windows 10

  • User by Fatima Wahab
  • Calendar Feb 2, 2018
  • Comment No Comments

A hosts file is a system file that is found on Windows, Linux, and macOS. On all three operating systems it serves more or less the same purpose; mapping domains to IP addresses. If you’ve never touched your Hosts file, chances are it’s just an empty TXT file on your drive which begs the question, what’s it for? Why do people need to modify the Hosts file? What happens when you add or remove something from this file?

The Hosts file is a relic from the old days of the internet. Back when DNS wasn’t a thing, these files were what translated a domain into an IP. Strictly speaking, they aren’t needed any more but they’ve still been kept around mostly for use in networking. What people generally use the Hosts file now for is to block certain domains though a host file can be used to redirect a website, naming devices on your network, and more. The host file essentially does what DNS does i.e. you give it a domain and an IP address and when you type the domain in your browser, the host file knows which IP to send you to.

Modify The Hosts File

You can modify the host file on Windows 7, 8/8.1, and 10 using the following method. The same rules apply. You will need administrative rights to modify the host file.

Hosts File Location

Go to the following location and look for a file named ‘hosts’.

It’s a simple text file though you will not see the TXT extension appended at the end. To open the file, right-click it, and select Notepad as the app to open it with.

Before you modify the hosts file, it’s a good idea to back it up somewhere. It’s rare that a modification to this file breaks anything serious. At the most, it can cause problems accessing certain websites. Regardless, having a backup is the easiest way to mitigate any problems. If you often modify the hosts file, it might be a good idea to keep a backup of each version.

To add a domain to the host file, you need the domain name, and its IP address.

Make sure you do not add http or https before the domain name. Simply add this line to the hosts file, save the change, and restart your browser. You can use a public IP to map a website or you can use private IP address and map a network system or server to its network address.

Block Domain

To block a domain, you need only the domain. You will redirect the domain to your own system. Open the hosts file and look for comment with localhost in it. This is your system.

Save the change, and restart your browser. A proxy can be used to bypass a domain blocked by the hosts file.

The following are the contents of an unmodified hosts file on Windows 10;

Hosts File Tools

There are lots of apps that modify the hosts file. They basically provide a GUI for what you can do with just the Notepad. If you’re nervous about modifying the hosts file, you can use one of these tools. Make sure you use a reliable one and compare the changes it makes later just to be on the safe side.

The hosts file in Windows contains mappings of IP addresses to host names, like an address book for your computer. Your PC uses IP addresses to find websites, so it needs to translate the host names into IP addresses to access websites.

When you enter a host name in a browser to visit a website, that host name is looked up in DNS servers to find the IP address. If you enter IP addresses and host names for websites you visit often, these websites will load faster, because the hosts file is loaded into memory when Windows start and overrides DNS server queries, creating a shortcut to the sites.

Because the hosts file is checked first, you can also use it to block websites from tracking your activities on the internet, as well as block ads, banners, third-party cookies, and other intrusive elements on webpages. Your computer has its own host address, known as its "localhost" address. The IP address for localhost is 127.0.0.1. To block sites and website elements, you can enter the host name for the unwanted site in the hosts file and associate it with the localhost address. Blocking ads and other undesirable webpage elements, can also speed up the loading of websites. You don't have to wait for all those items to load.

The default hosts file that comes with Windows does not contain any host name/IP address mappings. You can add mappings manually, such as the IP address 74.125.224.72 for www.google.com. As an example of blocking an ad server website, you can enter the following line in your hosts file to block doubleclick.net from serving you ads.

127.0.0.1    ad.doubleclick.net

NOTE: You can use the entries in the hosts file to block entire sites, not portions of sites. If there are ads served to you by the site you are viewing, they cannot be blocked without blocking the whole site.

To manually add entries to the hosts file, you can open the file (C:\Windows\System32\drivers\etc\hosts) in a text editor like Notepad.

NOTE: The hosts file has no extension.

However, an easier way to edit the hosts file is to use a free tool called Host Mechanic. This tool allows you to add entries to the hosts file, revert back to the default hosts file, and delete the hosts file.

Host Mechanic does not need to be installed. Simply extract the .zip file you downloaded (see the link at the end of this article) and double-click on the Host Mechanic.exe file.

01_running_host_mechanic

If the User Account Control dialog box displays, click Yes to continue.

NOTE: You may not see this dialog box, depending on your User Account Control settings .

02_uac_dialog

To add an entry to the hosts file, enter the host name for the site in the Site edit box. If you're entering a site you want to block, click the 127.0.0.1 check box. Otherwise, enter the IP address for the site in the IP Address edit box. Click Add to Host.

See Microsoft's page about resetting the hosts file for the initial text that should be in the default hosts file for the different versions of Windows (XP, Vista, 7, Server 2003, and Server 2008).

NOTE: Remember the hosts file should just be named "hosts" with no extension.

NOTE: When using Host Mechanic, you might see a malware warning message. The AskVG website, who provides this software, says it's a false positive. It modifies a system file, so some security software programs might incorrectly detect it as being suspicious. However, it seems safe to use.

Managing the Hosts file in Windows 10

how to add ip in host file in windows 10

Will Read more August 2, 2021

The hosts file is a computer file used by an operating system to map hostnames to IP addresses. It is a plain text file, conventionally called hosts . In Windows 10 this is no different. Wikipedia defines the purpose of the Hosts file as: “The hosts file is one of several system facilities that assists in addressing network nodes in a computer network. It is a common part of an operating system’s Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network.” ths

Hosts file primarily consists of lines of text depicting IP address within the first block of text, followed by one or more host names(i.e. google.com). Each of the fields is separated by a white space- tabs are preferred over space for formatting reasons, although spaces can also be used. Comment lines must begin with a hash (#)

The Hosts file has larger applications in internet resource blocking and redirecting local domains. For example, some web services,intranet developers and administrators define locally defined domains in a LAN for various purposes, such as accessing the company’s internal resources or to test local websites in development. Any security concerns regarding hosts file are that they may present themselves as a vector for malignant software; this leads to the file being modified by Trojan horse software or computer viruses to deflect traffic from intended havens to sites hosting malignant contents. For example, the widespread computer worm Mydoom.B blocked users from visiting sites about computer security and antivirus software and also affected access from the compromised computer to the Microsoft Windows Update website.

Generally, most computer users will never have the need to alter their hosts file, but occasionally the need does arise. To alter these files, one first needs to identify these files. Buried deep inside the folders of Windows 10, it is a text file, but doesn’t have .txt extension. It can be found by navigating to the path

C:WindowsSystem32Driversetc.

manage-hosts-file-in-windows10

Usually when open, the file won’t have but a few lines by default.. By visiting through the path mentioned above, a window will pop up depicting the hosts file along with some other files like protocol, networks and lmhosts.sam.

Modifying or editing this hosts can be done by following the steps below. Before modifying this file, make sure that administrator privilege is available, as only administrators can modify / edit these files. You may also want to disable Antivirus software temporarily, as this might get flagged as a suspicious activity

– After all these, right click on file, and open with notepad. Next as per requirements, a whole range of functions can be performed:

manage-hosts-file-in-windows10

Blocking a site on Windows 10 : For blocking access to any particular site, adding of entry at the end of the hosts file like 127.0.0.1 blocksite.com (where blocksite.com is the URL that you want to block) will do the necessary bits.

manage-hosts-file-in-windows10

Unblocking a site on Windows 10 : Just the opposite of the above step, select the URL pathway, delete the pathway, and save.

Locking the Hosts file : As mentioned earlier, sometimes hosts file may present itself as an easy target for virus and trojan attacks. Instances of these can be seen when traffic is diverted from intended destinations to other malicious websites. In cyber communities, this is popularly known as Hosts File Hijacking. Two methods can be employed for obstructing this:

  • The first option is a simple installation of a trusted and reputed antivirus software.
  • However, to add an extra layer of security, the locking of the hosts file can be done to prevent any other users or programs from modifying it. To perform this action, right click on the hosts file with Windows Explorer, visit properties at the bottom of the menu, and make it a Read Only file by selecting the option from the Properties dialogue box. Then hit OK.

manage-hosts-file-in-windows10

Sometimes, even with administrator credentials, an error message reading or Cannot create the C:WindowsSystem32driversetchosts file. Make sure that the path and file name are correct can be displayed. In such cases, visit Notepad from Start Menu, and select Run As Administrator. This will allow administrator credentials to appear, and necessary changes to hosts file can be made.

Windows 11 edit hosts file

How to edit HOSTS file on Windows

Do you need to edit the hosts file? Here's how on any supported version of Windows.

Avatar for Mauro Huculak

  • To edit the “Hosts” files on Windows, open PowerToys > Host editor , and click “Launch Hosts File Editor,” “Accept,” and “New entry.” Then, create the entry with IP address, hostname, and comment, turn on the “Active” option, and click “Add.”
  • To edit the “Hosts” file from Notepad (admin), open File > Open , and browse to the “C:\Windows\System32\Drivers\etc” location and open the “hosts” file. Add a new IP address and domain mapping – for example, 127.0.0.1 domain.com .
  • If you can’t edit the Hosts file, it’s because you need administrative permissions on Windows 11.

On Windows 11 (and 10), you can edit the “Hosts” file to manually override the system’s Domain Name System (DNS) settings for a specific internet domain (website) or device connected to the local network.

Usually, you don’t have to worry about manually mapping an IP address to a domain name using the Hosts file located in the C:\Windows\System32\Drivers\etc path on Windows 11. (It’s the same path on Windows 10 .) However, it can come in handy in many scenarios. For instance, when you want to block certain websites. When you don’t have a local DNS server in the network, you must map an IP address to a computer name or prepare a website transfer to a new hosting provider.

Regardless of your reason, Windows 11 and Windows 10 make it super simple to edit the Hosts file using Notepad or any other text editor as long as you open the app as an administrator. Otherwise, you won’t be able to edit the file. In addition, the PowerToys app includes a tool that makes it easier to manage entries in the Hosts file. Alternatively, you can also use Command Prompt to edit the Hosts file.

In this guide , you will learn the steps to modify the Hosts files on Windows (11 and 10) to map host names to IP addresses.

Edit Hosts file on Windows from PowerToys

Edit hosts file on windows from notepad, edit hosts file on windows from command prompt.

To edit the Hosts files with the PowerToys editor, use these steps:

Open PowerToys .

Click on Hosts File Editor .

Under the “Activation” section, click the “Launch Hosts File Editor” option.

PowerToys Hosts File Editor

Click the Accept button for the warning.

Click the New entry button.

Hosts File Editor new entry

Confirm the IP address, hostname, and comment (as necessary).

Windows 11 edit Hosts file

Turn on the Active button.

Click the Add button.

  • (Optional) Right-click the entry and choose the “Delete” option for a specific configuration.

After you complete the steps, the Hosts file will save with the new entries, and you should now be able to test the new configuration. In the editor, you can enable or disable entries with a toggle switch.

To edit the “Hosts” file on Windows with Notepad, use these steps:

Open Start .

Search for Notepad , right-click the top result, and select the Run as administrator option.

Click on File and select the Open option.

Browse to the Hosts file location: 

Use the drop-down menu next to “File name” and select the “All Files” option.

Select the Hosts file.

Open hosts file

Click the Open button.

In a new line, enter the IP address of the remote server, add at least one space, and confirm the domain name or computer name to reach the service. For example, 159.223.126.251 google.com #This PC redirects Google.com to the specified IP address .

Windows 11 edit hosts file

(Optional) Delete the entire line to remove the entry from the Hosts file.

Click on File .

Select the Save option.

Once you complete the steps, you can test the changes by opening Command Prompt and using the ping command to ensure the host is reachable.

If you want to block your computer from accessing certain websites, you can use the loopback address (127.0.0.1) followed by the domain name (127.0.0.1 website.com). Also, if you can edit the “Hosts” file on Windows 11, it’s because you need administrative permissions.

To edit the “Hosts” file through Command Prompt, use these steps:

Search for Command Prompt , right-click the top result, and select the Run as administrator option.

Type the following command to add another entry to the Hosts file and press Enter :

In the command, replace “159.223.126.251 google.com” for the entry you want to include in the file.

Command Prompt edit Hosts

(Optional) Type the following command to confirm the changes and press Enter :

After you complete the steps, the entry will be added to Hosts file. 

Since the Hosts file is a text file, if you want to remove an entry, the easiest way to complete this configuration from Command Prompt is to run the notepad %SystemRoot%\System32\drivers\etc\hosts command to open the file and delete the line to remove the entry and save the file.

Update April 22, 2024: This guide has been updated to ensure accuracy and reflect changes to the process using Command Prompt.

how to add ip in host file in windows 10

Multiple threat actors exploit a recently disclosed security PHP flaw CVE-2024-4577 to deliver multiple malware families.

The Akamai Security Intelligence Response Team (SIRT) warns that multiple threat actors are exploiting the PHP vulnerability C VE-2024-4577 to deliver multiple malware families, including Gh0st RAT , RedTail cryptominers, and XMRig.

“Threat actors continued the speedy-time-from-disclosure-to-exploitation trend and were quick to leverage this new vulnerability — we observed exploit attempts targeting this PHP flaw on our honeypot network within 24 hours of its disclosure.” reported Akamai.

The flaw CVE-2024-4577 (CVSS score: 9.8) is a PHP-CGI OS Command Injection Vulnerability. The issue resides in the Best-Fit feature of encoding conversion within the Windows operating system. An attacker can exploit the flaw to bypass protections for a previous vulnerability, CVE-2012-1823, using specific character sequences. Consequently, arbitrary code can be executed on remote PHP servers through an argument injection attack, allowing attackers to take control of vulnerable servers.

Since the disclosure of the vulnerability and public availability of a PoC exploit code, multiple actors are attempting to exploit it, reported Shadowserver and GreyNoise researchers.

In June, the U.S. Cybersecurity and Infrastructure Security Agency (CISA)  added  the the vulnerability to its  Known Exploited Vulnerabilities (KEV) catalog .

Greynoise researchers also  reported  malicious attempts of exploitation of the CVE-2024-4577.

“As of this writing, it has been verified that when the Windows is running in the following locales, an unauthorized attacker can directly execute arbitrary code on the remote server:

  • Traditional Chinese (Code Page 950)
  • Simplified Chinese (Code Page 936)
  • Japanese (Code Page 932)

For Windows running in other locales such as English, Korean, and Western European, due to the wide range of PHP usage scenarios, it is currently not possible to completely enumerate and eliminate all potential exploitation scenarios.” continues the advisory. “Therefore, it is recommended that users conduct a comprehensive asset assessment, verify their usage scenarios, and update PHP to the latest version to ensure security.

Akamai researchers also observed threat actors behind the DDoS botnet Muhstik exploiting this vulnerability.

The botnet shell script downloads an ELF file named “pty3” from a different IP address, likely a sample of Muhstik malware. The malware was designed to targets Internet of Things (IoT) devices and Linux servers for cryptomining and DDoS purposes. The bot also connects to the command and control domain p.findmeatthe[.]top, which was observed in Muhstik botnet activities, and communicates via Internet Relay Chat.

The researchers also observed a campaign abusing the exploit to deliver the XMR Rig. The attackers injected a command that relies on a PowerShell script to download and execute a script to spin up XMRig from a remote mining pool. The script also cleans up the temporary files for obfuscation.

“Between the use of various automation tools and a lack of corporate oversight, attackers are set up to succeed. The continuously shrinking time that defenders have to protect themselves after a new vulnerability disclosure is yet another critical security risk.” concludes the report. “This is especially true for this PHP vulnerability because of its high exploitability and quick adoption by threat actors.”
