The point of communication is to get an idea across; if most of the people you communicate with don't understand slash notation, then you use terms they're familiar with even if they're imprecise or inaccurate.
That is a very dangerous thing to say (or worse, do). Being inaccurate too often means it becomes impossible to be precise when you need to, because the terminology becomes ambigous after being used wrong all the time. That doesn't imply you should teach everyone who talks about a "class C" when they mean a "/24" about CIDR and VLSM, but it's not much harder to say "Your new class C sized address range is 96.112.30.0 - 96.112.30.255" rather than "Your new class C net is 96.112.30.0" which is at least incorrect and maybe even ambigous (then what's the netmask?).
I think NANOG's ISP-centric membership may skew the perception of our lexicon's state. Most network operators are not ISPs.
Ok, if I connect to their network I'll remove "ip subnet-zero" and "ip classless" from my configs to revert to the defaults that still reflect the pre-1993 state of affairs, but if they want to connect to "our" network, they should play nice and follow the rules we use here. Iljitsch van Beijnum
