[WEB4LIB] what kind of URL is this?

You can take any IP address and put it through the following formula

(a*256^3)+(b*256^2)+(c*256)+(d*1)

where a is the first # in the IP address, b the second, c, the third, d the
fourth.
where 256^3 is 256 cubed, 256^2 is 256 squared

Example:

199.45.145.1

199 * 16777216 = 3338665984
45 *  65536 =  2949120
145 * 256 = 37120
1 * 1 = 1

3338665984 + 2949120 + 37120 + 1 = 3341652225

Therefore http://199.45.145.1 = http://3341652225

Unfortunately, I don't know enough math to reverse the process, if it is
even possible.

One use for using an address such as this is to get around filters and
proxies.
