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.
