The address "classes" have been absolete for about 5 years. Don't think
of addresses in terms of Class A, B, and C's, think of them as CIDR
blocks. When someone says a "class C" they probably just mean a /24, same
with a B (/16).
For example my company commonly refers to the "Class B" we've been
assigned, which comes out of the 64.0.0.0 class A. The class A really
doesn't mean anything anymore as ARIN hasn't assigned blocks of IP
addresses as classes for a very long time.
So saying "how can you summarize a bunch of Class C's with a class
B?" .. well ofcourse you can. You're just summarizing a bunch of
/24's with a /20 subnet mask.
