To Access blocked sites: Use Calculator!!

To Access blocked sites: Use Calculator!!
When both Domain Name & IP Address are banned, Use Calculator to Access that Website

This unique Mathematics based trick will probably work when websites are blocked in your institution or corporate network based on the host name or their IP address.
The trick is to convert the human readable website address that's blocked (like Link:) into an IP address (208.75.184. 160) and again translate this value to a decimal address which is probably not blocked by the website filters.
Here's a step by step guide to render Link:. com to a decimal address:

How to Access Restricted Websites
1) get its IP address (216.178.39. 74), by pinging the name (if you have a direct internet connection) or if you only have access via a web proxy then find it out by using a networking website like network-tools. com.
2) start your PC's calculator, and change it to scientific mode (using the "View" menu)

3) enter each of the four IP octets, one by one, converting them to binary (enter number and click on the "Bin" radio button)
Thus 216.178.39.74 becomes
216 = 11011000
178 = 10110010
39 = 00100111
74 = 01001010
Notice how any binary numbers less than 8 digits long have had leading zeroes added to pad them out. Reassembled into IP address order, you get 11011000.10110010. 00100111. 01001010
4) Remove the dots, so you get one huge line of binary, thus: 1101100010110010001 0011101001010
5) Copy this binary string
6) Go to your scientific calculator, and hit the "Bin" button FIRST (as you are about to enter binary), THEN paste in the binary string.
7) Click on the "Dec" button on your calculator, and you will get the converted value of 3635554122
8) Add the hypertext protocol prefix and paste into your browser's address bar: Link:
Wuntoo adds: I used to be in a place that had websense, where both website names and their corresponding IP addresses were blocked. However was able to get limited access by converting the IP address to decimal, which websense (at the time) did not know about. This might have changed since, or if your school runs an old version it might still work. Note that if you surf away from the page you might hit websense blocks again unless you manually reconstruct the next address you want to get to.
How to access Bebo, Myspace that are blocked?

The most common websites that are blocked in schools include Bebo, MySpace, Hi5, Xanga, Orkut, Facebook and in some cases, Youtube. We share a couple of options to bypass the internet ban and they includes using proxy servers, special mobile websites and screen sharing software:

Trick A: Most solutions to unblock websites suggest using web proxies to bypass restrictions. Link: has a comprehensive list of public anonymous web-based proxy servers that you may want to try.

But chances are that your school administration has already blocked access to most proxy servers as well. In that case, you have some more options:

Trick B: Surf the web using Link:, a new service that's free and converts any website into a mobile phone friendly format. The other option that may help access blocked website is Link:, a miniature web browser that is meant for embedding inside other web pages. Another solution may be Link:.

Trick C: Finally, a option that will always work provided you have your sister or mom at home to help you - Use a screen sharing software like Link:, Link: or Link:.

Ask someone at home to accept your screen sharing invitation request and browse the web at school using your home computer. This will enable you to access any website or instant messenger like Skype or Yahoo from the school or work computer. You may also try remote control software that comes with Win XP Pro instead of screen sharing apps to access restricted sites.

If Google Talk is blocked by your employer, use the Link: and connect with Google Talk buddies outside the office firewall.

Accessing unauthorized web sites using the above tricks may be considered a violation of school or work policies and might put you in trouble. Use them at your own risk.
