network ID for multiple physical networks. Routing outside of the site continues by
dividing the IP address into a net ID and a host ID via the class. Inside a site, the subnet
mask is used to redivide the IP address into a custom network ID portion and host ID.

needs to communicate with a node on another network, a gateway transfers the data
between the two networks.
