Network Addresses

As with the MAC sublayer, devices need to determine what packets are destined for them and where they came from. However, routing in the network layer is often hierarchical. In other words, the network may be divided into pieces or subnetworks, so network addresses must accommodate the feature. In a network address, a portion of the address is used to designate the subnetwork and another portion identifies a particular station in that subnetwork. The two most common forms of network addresses are those defined by ISO and the IP protocol.
