You've been reading too much Cisco Press material.
All a "Class A" gives you today is filthy looks, and people who know
better shake their heads, feeling sorry for you.
The operational world left classful IPv4 addressing behind us, over
a decade ago.
Perhaps it's time that certain vendors did the same, in their literature
and certification programmes.
Recycling outdated terms to apply to new concepts ("Class C" to represent
a /24 in the CIDR IPv4 world, or a /48 or whatever in IPv6) is a folly
that can only lead to suffering.
