Access Facebook/Orkut If blocked in Your School College Or Office

Did you try to access Facebook or Orkut account when you are in school, college or office? You must found that you are blocked when you are trying to access them, mainly social networking sites. Most of the organizations block the social networking websites to prevent people from access them.

Tip: Bulk Download Facebook Album photos

If you are a very big fan of Facebook or Orkut like me then you must have tried some methods to access those blocked websites. But don’t worry! There are various ways to access the blocked websites. I’ll describe the methods. But for your knowledge, I want to say how the administrator of the network system blocks the Facebook, Orkut or  any other?

The urls of the website, you generally type in the address bar are originally an IP address. Every website has an unique IP. So when you browse any website typing the website url, computer matches the url name with its IP address. This job is done by the DNS server. DNS server is a computer, registered with the network which keeps the data of all the websites and corresponding IP addresses. So if any body blocks the IP address in DNS server then all the client of that DNS server won’t have the access that website. Here the tricks plays.

The Facebook, Orkut are blocked in your college or office because the administrator has blocked site in the DNS server. So now you can easily imagine that what I’m going to do. To unblock the site you can use another DNS server. It is quite easy. You can use OpenDNS servers or Google Public DNS servers.

If you are using Windows then go to Control Panel > Network and Internet Connections > Network Connections and then right click on connection status icon which you are using to access internet. Now chose “Properties” and then Internet Protocol(TCP/IP).

Put any one of the  following values in the DNS server address

OpenDNS server address:

208.67.222.222
208.67.220.220

Google DNS server address

8.8.8.8
8.8.4.4

Make sure that your institution or office is not using the DNS server which you going to use. Once you changed the DNS server you can access facebook, Orkut or any other websites you want.

If you know any other way then share with me.
