Question

Quizplus · Accepted Answer

For a Class C IP address, the first three octets (24 bits) are reserved for network addressing and the last octet (8 bits) is for host addressing. The subnet mask for Class C is 255.255.255.0, which means that the first 24 bits are used for network addressing and the last 8 bits are used for host addressing within that network. A subnet mask of 255.255.255.255 would be a broadcast address and not a valid subnet mask. A subnet mask of 255.0.0.0 or 255.255.0.0 is used for Class A or Class B IP addresses, respectively.
