Which of the following is a valid host address in the Class C network 192.168.100.0?

Explanation:
In a Class C network using the default 255.255.255.0 mask, the first address of the subnet is the network address and the last address is the broadcast. For 192.168.100.0/24, usable host addresses are in the range 192.168.100.1 through 192.168.100.254. Therefore, 192.168.100.1 is a valid host address. The address 192.168.100.0 is the network address and cannot be assigned to a host. The address 192.168.100.255 is the broadcast address and also cannot be assigned to a host. The address 192.168.100.256 is invalid because an octet must be between 0 and 255.
