This means that whenever your computer tries to connect to the domain (for example) "www.facebook.com", it will not ask the DNS for its IP address and will instead consider 0.0.0.0 as the IP address of "www.facebook.com". facebook.com”.
127.0.0.1 is a special address, called a loopback IP address and if a public switch, router or gateway receives a packet addressed to the loopback IP address, it is required to drop the packet without saving the information.
We have therefore made the domain “www.facebook.com” inaccessible in our example.

Steps to block domains and subdomains using hosts file:
1. Once your hosts file is open, enter a comment in your hosts file to organize your IP address mappings to host names.
2. To add a comment, make sure you are on a new line and type /"#/" followed by your comment details. The /"#/" symbol will tell your computer to ignore anything that comes after /"#/" on the same line
3. Then, still on a separate line, enter 0.0.0.0 and a space followed by your domain name or subdomain name (website address) to block.
For example:
#Block Facebook
0.0.0.0 www.facebook.com
4. In the above example, www.facebook.com (domain name) will be blocked by the hosts file. To save these entries, go to the top left corner to file, left-click on it and left-click Save.
5. Open your browser and navigate to the website URL you just added to your hosts file. The blocked website will now be inaccessible, which means it has been blocked successfully.
