Start your PC's calculator, and change it to scientific mode for XP and Programmer mode for windows 7 (using the "View" menu)
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.
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 for other 3 numbers as well. You will get four 8-digit binary equivalents. Put them all together
Thus 184.108.40.206 becomes
69 = 1000101
171 = 10101011
224 = 11100000
11 = 1011
· 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 1000101.10101011.11100000.1011
· Remove the dots, so you get one huge line of binary, thus: 100010110101011111000001011
Copy this binary string
· Convert 100010110101011111000001011 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
