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 Windows hosts file:
1. Once you have your Windows 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 windows 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.

hosts file default contents:
# Copyright (c) 1993-2009 Microsoft Corp.

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#102.54.94.97 rhino.acme.com # source server
#38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
