What is the total number of unique host addresses in a Class A network?

Explanation:
In a Class A network, the default subnet mask is 255.0.0.0, which leaves 24 bits for host addresses. That means there are 2^24 possible host addresses within a single Class A network, equal to 16,777,216. If you were counting only usable hosts (excluding the network and broadcast addresses), it would be 16,777,214. The question asks for the total number of unique host addresses, so 16,777,216 is the correct total.
