Block any website on your system..!!!

Sometimes you needed to block any explicit website or social networking site in offices...So,you may setup firewall filters to do this. But, here is a simple trick to block the site on your system.
=>Here are the steps...
1. Go to the location C:WINDOWSsystem32driversetc
2. You will find a file by name "hosts" with no extension.
3. Open that file in "Notepad"
4. Go to the bottom of the page where you could find the following line " localhost"
5. Now add another line at the bottom for ex: " localhost"
6. This line will block the site

=>The trick behind this is that the is the IP address of local system the system. Now when you enter a site the browser will first check the hosts file and then it would go for the DNS service of your ISP.
Now we have added the IP address of the xyz site as, so the browser will assume that is the IP address of the xyz site and will connect to the local host itself and so the websites doesn't get opened...
