Umm, yes, by definition:
Class A addresses: 1.0.0.0-126.0.0.0 (broadcast and network included)
Class B addresses: 128.1.0.0-191.254.0.0 (broadcast and network
included)
Class C addresses: 192.0.1.0-223.255.254.0 (broadcast and network
included)
The addresses you speak of are a series of contiguous Class C addresses.
Merely because you are defining the entire Class C range of 200.*.*.*
does not make it a class A network. We're not talking about
supernetting either.
Sure, we're arguing semantics but just by defining a set of conditions
based merely on the first octet of an IP address still does not make it
a class A network. If you don't believe me ask a router.

Umm, no, they are indeed class A, i.e., 200.*.*.*. If a class C needed
to
be blocked, it would be something like 192.168.0.* or 192.168.100.*.
So, class A = 192.***.***.*** 16,581,375 addresses
class B = 192.168.***.*** 65,025 addresses
class C = 192.168.100.*** 255 addresses
