See http://en.wikipedia.org/wiki/IP_address#IP_version_4_addresses

That will show you that the first octet of an ipv4 IP address can range from

1 - 223

For classes A, B, and C.

Just out of the curiousity, is there any good rationale for having it this way?

Boris.


Having it what way? Do you mean class A, B & C etc.? If so, it was an early attempt to achieve some measure of efficiency in that you'd be given an appropriate size block. However, address classes are depreciated with classless addressing. This means you can (in theory) get any size block of addresses. The class D range is still used for multicast traffic and E is resverved for future use.
