Explanation

A Class C network uses a /24 prefix (subnet mask 255.255.255.0), which provides 256 total addresses (2^8). However, the first address is reserved as the network address and the last is reserved as the broadcast address, leaving 254 usable host addresses. The value 255 is the total before subtracting the two reserved addresses, making 254 the correct maximum number of unique (assignable) host addresses.
