1 How to obscure a URL http://www.pc-help.org/obscure.htm Start with an IP address. In this example we'll use 206.191.158.55. Enter the following keystrokes into the calculator exactly as shown: 206 * 256 + 191 = * 256 + 158 = * 256 + 55 = The dword equivalent of the IP address will be the result. In this case, 3468664375. Now, there is a further step that can make this address even more obscure. You can add to this dword number, any multiple of the quantity 4294967296 (2564) -- and it will still work. This is because when the sum is converted to its basic digital form, the last 8 hexadecimal digits will remain the same. Everything to the left of those 8 hex digits is discarded by the IP software and therefore irrelevant. Thus, the following URLs will also lead to this page: http://7763631671/obscure.htm http://16353566263/obscure.htm http://235396898359/obscure.htm 2008-04-11 20:57:51.0 2008-04-11 20:57:51.0
