Hosts file is used to resolve domain names without using Domain Name System (DNS).
This means that whenever your computer tries to connect to the domain (say) 'www.facebook.com' it will not request DNS for its IP address and instead consider 0.0.0.0 to be the IP address of 'www.facebook.com'
127.0.0.1 is a special address, called loopback IP address and If any public switch, router, or gateway receives a packet addressed to the loopback IP address, it is required to drop the packet without logging the information.
So, we have made domain 'www.facebook.com' unreachable in our example.

Steps to block domains & subdomains using hosts file:
1. Once you have your hosts file open, enter a comment in your hosts file to organize your mappings of IP addresses to host names
2. To add a comment, make sure you're 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. Next, again on a separate line, enter 0.0.0.0 and a space followed by your domain name or subdomain name (website address) to be blocked.
For example:
#Block Facebook
0.0.0.0 facebook.com
4. In the above example facebook.com (domain name) will be blocked by the hosts file. To save these entries, navigate to the top left hand corner to file, left click on it and left click on save.
5. Open up your browser and navigate to the website URL address you have just added to your hosts file. The blocked website will now be unreachable meaning that it has been blocked successfully.
