How to obscure a URL
http://www.pc-help.org/obscure.htmStart 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:
