There are three parts of an IP address: Network Portion, Host Name, Subnet Mask.

Explanation:
An IP address is interpreted by splitting it into a network portion and a host portion, with the split defined by the subnet mask. The subnet mask isn’t itself part of the address; it’s a separate value that tells routers how to separate the address into the network bits and the host bits. “Host Name” isn’t a part of the IP address—that term comes from DNS, which maps names to numbers, not from the address format itself. Likewise, a gateway is a routing device, not a component of the address. So the correct description is the Network Portion and the Host Portion, using the Subnet Mask to define where the division lies.
