There are many reasons why someone wants to block certain websites.

what is Hosts File?

A Hosts file is a plain text file in an operating system which is used to map hostnames to the IP addresses of the given website. Let me explain how it works.

For example, if you want to launch [hostname]. Usually, the computer checks the Hosts file first to find corresponding IP address of the hostname.

If the search is successful, it uses the mapped IP address. If the search is not successful, it finds the IP address of the hostname by sending a query to the DNS(domain name system).

Here, we are going to map the hostname to your localhost IP address so that it cannot search for the actual IP address of the hostname this way browser cannot connect to the website hence it shows refused to connect. So this way hosts file can be used to block certain websites.
