This is an odd one; it doesn't have anything to do with DNS. Here's how it works:

"www.theactualaddress.com" resolves to an IP address, such as 192.168.0.1. An IP address is normally represented by a series of four decimal numbers between 0 and 255, called "octets" for the fact that each equates to a binary number with 8 digits. The IP address is actually a 32-bit integer. The 4-octet (4x8-bit) representation is simply an easier way to read it. So 192.168.0.1 can be translated to
((1 * 256^0) + (0 * 256^1) + (168 * 256^2) + (192 * 256^3)), or
((1 * 1) + (0 * 256) + (168 * 65536) + (192 * 16777216)), or
(1 + 0 + 11010048 + 3221225472), or
3232235520

You could probably use WebSTAR's Virtual Hosts manager to recognize when the address has been written in decimal (as a virtual hostname) to route such requests to whatever root folder you want. You could also use Welcome to alter the path as indicated above, removing the "abc".
