I'm going to contradict you there. Classful addressing had a lot to recommend it. The basic problem we ran in to was that there weren't enough B's for everyone who needed more than a C and there weren't enough A's period. So we started handing out groups of disaggregate C's and that path led to the swamp.
the swamp preceeded cidr and, if you had a bit of simple arithmetic clue, you would realize that, unless you are prescient, you will always run out of some classes before others. as we are very poor at predicting the future, there was no win to be had in classful. randy
