How to block websites

I found this tutorial when I tried to search on how to block website. This tutorial doesn't need any software. It is also easy to edit which website to block.

Step-by-Step guide:

1. Browse 'C:\WINDOWS\system32\drivers\etc'

2. Find the file named 'HOSTS'

3. Open it or drag it in 'Notepad'.

4. Under '127.0.0.1 localhost' Add '127.0.0.2 www.sitenameyouwantblocked.com' , and that site will no longer be accessible.

127.0.0.2 = ip address to block
www.sitenameyouwantblocked.com = website URL

Note:
For every site after that you want to add, just add "1" to the last number in the internal ip (127.0.0.2) and then the add URL.
