Tricks to block websites without any Software

Nowadays children are addicted to social networking sites such as Facebook, Twitter, Youtube etc. Due to this they are affected by various health problems and their studies are also affected. If you want your children not to open a particular website, you can easily block that site. Here I have given a trick on how to block websites without any software.

• Browse C:\WINDOWS\system32\drivers\etc
• Find the file named "HOSTS"
• Open it in notepad
• Under "127.0.0.1 localhost" add 127.0.0.2 www.sitenameyouwantblocked.com. 

Ex:- If you want to block Facebook then type 127.0.0.2 www.facebook.com. Then www.Facebook.com will no longer be accessible.
