Seriously... I'm not sure that the teachers I had for networking and systems admin had ever heard of CIDR.
The textbooks hadn't. It was a nice bump in the learning curve when I hit the real world.
I've never seen a text book which had any relevance to modern networking which didn't cover CIDR.
Sadly, most texts I've read, and certainly all the current courseware I've looked at, still teach classful addressing and subnetting as the primary method with a sidebar on CIDR as the "new" method.
Perhaps if we all made a conscious effort to avoid using the term, new people who are learning from the examples they see around them would stop picking up on it as "how things work".
History is nice, but not knowing when to give up and move on is just sad.
The term class C sticks because it's so useful; you'll note that class [AB] aren't used much colloquially. This is how English evolves. S
