How to block a website using Host File?

To block the website using the Host File, just follow the instructions given below.

Open the host file in the Notepad, by following the above method.
At the bottom of the file, in a blank space, type 0.0.0.0 followed by the website’s IP address.

Let us understand it with an example — I want to block, let us say, twitter.com. So, I navigate to the bottom of the notepad and there I type 0.0.0.0 twitter.com. This will block twitter.com as you can see from the screenshot below.

Similarly, as you can see from the screenshot, I have blocked Facebook as well as an adult website by applying this method.

However, I cannot block YouTube from this method.
