Answer: 16,777,216
A class C network has 2^24 (16,777,216) IP addresses. This is because the first three octets (groups of 8 bits) in the IP address are reserved for the network address, and the final octet is used for the host address. Since there are 8 bits in an octet, this means that there are 2^8 (256) possible values for each octet. In a class C network, the first three octets are set to a specific value, so there are only 2^8 (256) possible values for the final octet, which corresponds to the host address. This means that a class C network has 256 x 256 x 256 = 16,777,216 possible IP addresses.
