[How To] Access Blocked Site Using Calculator

If you found out that you can't have access to your facebook profile using school network that blocked (restricted) certain websites. "When there's a will, there's a way!"

1. Open Command prompt and type ping facebook.com
You will see the IP address as shown below.

IP address of facebook.com = 69.171.224.11

2. Start your PC's calculator, and change it to scientific mode for XP and Programmer mode for Windows 7 (using the "View" menu)

3. Convert each of the 4 numbers (69, 171, 224 and 11) into an 8-digit binary value. In order to do this open your Windows calculator, select Scientific view.

4. Make sure 'Dec' is selected and enter the first number and select 'Bin'. This would give you 8 digit binary value of 69 = 1000101 .
Repeat the process of 3 numbers as well. You will get four 8-digit binary Equivalent. Put them all together.

5. Notice how any binary number less than 8 digit long have had leading zeroes added to pad them out. Reassembled into IP address order, you get 1000101.10101011.11100000.1011

6. Remove the dots, so you get one huge line of binary, thus 100010110101011111000001011
Convert this into a decimal value. Select Bin and input 100010110101011111000001011 (copy-paste) and then Click on the 'Dec' button on your calculator, and you will get the converted value of 73055755

7. Add the hypertext protocol prefix and paste into your browser's address bar: http://73055755
This should open http://facebook.com
