Do you *really* want somebody working on your network that gets confused by a
reference to 213/8 because it's in Class-C space? Either they haven't taken
the 20 minutes it takes to learn how CIDR works, or they're unable to learn it.
Either way, they shouldn't be working on your network.
And "Cisco is still teaching it" is *not* an excuse - I'd expect a competent
network engineer to show enough intellectual curiosity to say "I keep seeing
references to 199.14/19, what the heck is that?" Heck, I've had Oracle DBAs ask
me about "What's this /22 network mask all about?" and explained it in under 5
minutes.
(Hint to Cisco and others - any training course that includes 'Class A/B/C' is
likely to be perceived as "dangerously last-century oriented". We had a
3rd-party training class on some Cisco fiberchannel directors, and the
instructor mentioned class A/B/C - and immediately lost a whole chunk of
credibility, making us wonder what *else* was being mis-taught).
Class A/B/C - modern networking's version of a brown M&M backstage at a Van
Halen concert.
