Editing the hosts file in Windows 11 is easier than you might think. It’s a small but powerful tool that lets you redirect web addresses. Whether you need to block a website or test a new server, you can do it by tweaking this file. Here’s a step-by-step guide to get you through it smoothly.
How to Edit Hosts File Windows 11
Editing the hosts file will allow you to control which domain names link to which IP addresses. Follow these steps to make changes.
Step 1: Open Notepad as Administrator
Right-click on Notepad and select "Run as administrator."
Opening Notepad with admin privileges is crucial because the hosts file is protected. If you skip this step, you won’t be able to save your edits.
Step 2: Open the Hosts File
In Notepad, go to the File menu, click Open, then navigate to C:WindowsSystem32driversetchosts.
The hosts file is stored in the "etc" folder. Make sure to change the file type to "All Files" in the Open dialog box, or you won’t see it.
Step 3: Edit the Hosts File
Add the lines you need, such as 127.0.0.1 www.blockedwebsite.com.
Each line consists of an IP address followed by a domain name. You can add as many lines as you need, but make sure each entry is on a new line.
Step 4: Save the File
Click File, then Save. Close Notepad.
Saving the file will apply your changes immediately. If you get an error, make sure you’re running Notepad as an administrator.
Step 5: Flush DNS Cache
Open Command Prompt as an administrator and type ipconfig /flushdns, then hit Enter.
Flushing the DNS cache ensures that your computer uses the updated hosts file. This step is essential for your changes to take effect right away.
After completing these steps, your computer will redirect the domains as specified in the hosts file. If you blocked a website, you won’t be able to access it anymore. If you redirected a domain, it will now point to the new IP address you specified.
