What is a Network Address?

             

            Network Address

                                     - an identifier for a node or host on a telecommunications network. Network addresses are designed to be unique identifiers across the network, although some networks allow for local, private addresses or locally administered addresses that may not be unique.Special network addresses are allocated as broadcast or multicast addresses. These too are not unique.

In some cases, network hosts may have more than one network address; for example, each network interface may be uniquely identified. Further, because protocols are frequently layered, more than one protocol's network address can occur in any particular network interface or node and more than one type of network address may be used in any one network.
