I actually think that CIDR is easier to understand than classful addressing. Do the subject completely in binary. It makes complete sense then. - Brian BTW: If the grad students don't get it, fail them! I don't want an engineer who can't grasp basic binary math.

The big problem here is that CIDR is tough to teach, even to engineering students. This seems bizarre and counterintuitive, but its true. I know this because I've done it. Its really easy to teach classful addressing, on the other hand. Other problems include the issue that many of the folks teaching have never had to use CIDR in real life, textbook age, and, in some cases, lack of mathematical preparation and inclination on the part of students.
Scarier: I was teaching graduate students.
