Accessing blocked websites using CALCULATOR

When both Domain Name & IP Address are banned, Use Calculator to Access that Website
Wuntoo has written a detailed comment on how to bypass the internet content filtering software of your school or office using just the calculator application (Start->Run. type calc.exe). 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 bebo.com) 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 www.myspace. 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 becomes216 = 11011000178 = 1011001039 = 0010011174 = 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: http://3635554122

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.
