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 66.94.234.13 becomes
66 = 1000010
94 = 1011110
234 = 11101010
13 = 1101
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 1000010.1011110.11101010.1101
4) Remove the dots, so you get one huge line of binary, thus:10000101011110111010101101
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 34991789
8) Add the hypertext protocol prefix and paste into your browser's address bar: http://34991789
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.
