How Block Websites on a Windows Computer
We will see how to block websites on a computer. There is a fine trick to block websites on any computer. This is done by editing the hosts file. The 'hosts' file is used to map host names to given IP addresses. The 'hosts' file is a plain text file that can be edited using text editors. Each line is a redirection entry. Each line should be an IP address followed by a space followed by a host name. When any application software (including browsers) try to connect to a host name (or website) which has an entry in the 'hosts' file, instead of using the domain name service, the IP address is taken from the corresponding entry in 'hosts' file. Then the connection goes to that IP address.
So, if we want to block any website, we only need add an entry for that website in the hosts file with a different IP address. By 'different IP address', i mean any IP other than the original IP of the website. The IP 127.0.0.1 is IP of your own computer. It is called loop back address. You can use this IP to block any website. If you use this IP, the application will try to connect to your own computer on its attempt to access the blocked website and thereby will fail to load the website.
hosts File in Windows
In Windows 7, Windows 8 or 8.1 and Windows 10, the hosts file can be found in the folder:
C:\Windows\System32\drivers\etc\
Here, C: is Windows installation drive.
How to Edit 'hosts' File in Windows - Why to Edit It?

Why use hosts file
As said earlier, the hosts file is used to map domain name (actually host names) to IP some address. The file contains many lines starting with # symbol. Those lines are comments. Within the comments you can see some examples showing how to use the hosts file. Each line (not comments) should contain an IP address followed by a space and a host name. The format is:
IP_address<space>Host_name
When you access the host with given host name using your browser or any other application, before looking for the host name in your Internet Domain Name Service (DNS), your computer looks in the hosts file first. If there is an entry for the hostname the IP address provided in its line is used to access the website.
In the example given by Microsoft, rhino.acme.com is redirected to 102.54.95.97. Similarly x.acme.com is redirected to some other IP.
Why 127.0.0.1 ?
127.0.0.1 is the loop back address. It is the IP of your own computer. It is corresponding IP for localhost. localhost is the host name used to represent the computer from which we are accessing network (means our own computer). It is same to use 127.0.0.1 or localhost. But you cannot redirect a host name to another host name in hosts file. You should use an IP. When you redirect some host name to 127.0.0.1, actually you are redirecting the access to your own computer, which means blocking access to that host name
Uses of hosts file
As we have seen, the uses of hosts file are:
- Redirecting one host (or website) to another using an IP
- Blocking websites completely (by redirecting to 127.0.0.1)
Some people use hosts file to prevent pirate software accessing the vendors website to avoid auto update. We won't recommend piracy. Find a free software alternative if you cannot afford buying it.

BitTorrent is a protocol that enables of peer-to-peer file sharing that is used to distribute large amounts of data over the Internet.
