Which old-style class of subnet would provide for 16,384 networks, with over 65,000 hosts per network?
A) Class A
B) Class B
C) Class C
D) Class D
E) Class is dismissed!
The answer: B) Class B
A class B subnet begins with an IP address of 128 through 191, and the mask of 255.255.0.0 can support over sixteen thousand networks with 65,534 devices per subnet. This old-style class-based subnet scheme was changed to classless inter-domain routing (CIDR) in 1993, which removed these static classes with a more flexible CIDR-based notation.
