How many numbers of addresses are usable for addressing in a Class C network? Answer: c. The number of addresses usable for addressing specific hosts in each network is always 2 power N - 2 where N is the number of rest field bits, and the subtraction of 2 adjusts for the use of the all-bits-zero host portion for network address and the all-bits-one host portion as a broadcast address. Thus, for a Class C address with 8 bits available in the host field, the number of hosts is Class A 0.
