How to Edit the Hosts File in Windows 11
Editing the Hosts file in Windows 11 lets you control website access and test server setups.
The Hosts file is a special system file found at 📁C:\Windows\System32\drivers\etc\hosts. It works like a personal address book for your computer, linking website names, like geekrewind.com, to their specific computer addresses called IP addresses.
This means your computer checks this file first, before asking the internet for directions to a website. You can use it to block websites, send traffic to a different address, or check how a local server acts before you put it online.
For example, you might use it to stop ads from showing up or to see how a new website works without it going live on the internet.
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 to block websites you don’t want to visit or to test websites you’re building on your own computer before they go live. It’s a way to tell your computer exactly where to find a website, which can also help fix some network problems.- Block websites: Stop your computer from visiting certain websites by redirecting them.

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