I would agree...... I always believed classfull meant it *does* end on an
8-bit boundary..... i.e. For Class A it's 255.0.0.0, for Class B it's
255.255.0.0, and Class C it is 255.255.255.0. Given that I would also agree
with Ed that the answer would be 172.18.255.255.
But hey! What do I know......... ya think ya know something, and WHAMO,
it's not quite as clear as one might have originally thought!
