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 doesnï¿½t 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 184.108.40.206 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.
4. Retrieve web pages via Email
Web2Mail is a free service that sends any websites into your inbox. All you need to do is send an email to email@example.com with the URL as subject title.
5. WayBack Machine
Wayback machine periodically keeps a copy of almost all websites on the internet from the date they have started. You can access your blocked site by fetching its latest copy from archives.
Screen-Resolution.com allows you to view any website in a different resolution. This could be an interesting tool to access blocked websites.
7. Google Mobile Search
