Editing the host file in Windows 11 is a quick way to control how your computer interacts with certain websites or servers by mapping specific IP addresses to particular domain names. Below, you’ll find a simple, step-by-step guide to accomplish this task, along with some helpful tips and frequently asked questions.
How to Edit Host File in Windows 11
Editing the host file in Windows 11 involves navigating to the file, opening it with a text editor, making your desired changes, and saving the file. This process allows you to control how your computer resolves domain names to IP addresses.
Step 1: Open Notepad as Administrator
Right-click on the Notepad icon and select “Run as administrator.”
Running Notepad as an administrator is crucial because the host file is a system file, and you need elevated permissions to modify it.
Step 2: Open the Host File
Navigate to C:WindowsSystem32driversetchosts.
To do this, in Notepad, go to File > Open, paste the path, and make sure you select “All Files” from the file type dropdown.
Step 3: Edit the Host File
Add your desired IP addresses and domain names in the format “IP address domain name.”
For example, you might enter “127.0.0.1 mywebsite.com” to block a website or redirect it to your local server.
Step 4: Save the Host File
Click File > Save to keep the changes.
Ensure you don’t use “Save As” because it might save the file with the wrong permissions or format.
Step 5: Verify Changes
Open Command Prompt and type “ipconfig /flushdns” to refresh the DNS cache.
This step ensures that your changes take effect immediately.
After completing these steps, your computer will start using the new IP addresses and domain names specified in the host file.
