How to Edit the Hosts File in Windows 11
You can edit the Hosts file in Windows 11 to control website access and test local server configurations.
The Hosts file is a system file located at 📁C:\Windows\System32\drivers\etc\hosts that maps domain names to IP addresses, overriding your normal DNS lookups.
Editing the Windows hosts file allows users to manually block specific websites, redirect website traffic to different IP addresses, or test local server behavior before deployment. For instance, users can employ the hosts file to block unwanted advertisements or to restrict access to a website currently under development.
Open Notepad as administrator, then type notepad.exe C:WindowsSystem32Driversetchosts into the Command Prompt. Edit the file, and save your changes via File > Save.
Why Would You Edit the Hosts File?
You can edit the hosts file in Windows 11 for several useful reasons, like blocking websites you don’t want to visit, testing new websites on your own computer before they’re public, or fixing network problems by telling your computer which IP address a website name should use.- Block websites: Stop your computer from visiting certain websites by redirecting them.
- Test websites: Web developers use the Hosts file to test websites on their own computer before making them live.
- Fix network issues: Sometimes you want to link a name to a specific IP address for easier local access.
Where is the Hosts File Located?
The Hosts file is stored in this location on your computer:
C:\Windows\System32\Drivers\etc\hostsWhat Does the Hosts File Look Like?
The hosts file in Windows 11 is a simple text document that lists IP addresses and website names, connecting them line by line; lines starting with a ‘#’ symbol are ignored and act as comments.

# 127.0.0.1 example.com (this line is ignored because it starts with #)
