Websites like facebook , twitter  and other social networking sites are generally blocked in schools, colleges and offices . There exist some tricks by which you can bypass  the restrictions and access blocked sites , the most obvious is the use of proxies or Anonymizer websites . But using proxies doesn’t always works as they gets blocked by firewall as well . Here I am listing some other methods to access blocked contents .

1. Use IP instead of URL

Each website has its equivalent ip address . This method works best when blocked sites are stored as a list of URLs  .You can use  ip address  to access blocked contents . For example to access facebook you can use  ip address 69.63.189.11 in your address bar . You can use ip-address.com to find the ip address of other websites .

2. Use Google Cache

All major search engines like Google yahoo and Bing stores cached pages of websites themselves . You can access blocked websites by viewing their  cached copy on search engines  .

3. Translations services

Translation services like Google Translate , translate a website from one language to another and  display the translated results on their own page .You can access the blocked website by re-translating  blocked url using such online translation services .
