A network address is an identifier for a node or network interface of a telecommunications network.

Network addresses are often designed to be unique across the network, although some networks allow for relative or local addresses that may not be unique.

More than one type of network address may be used in any one network.

In some cases terminal nodes may have more than one network address, for example, each link interface may be uniquely identified. In addition, non terminal nodes are often assigned network addresses. Further, because protocols are frequently layered, more than one protocol's network address can occur in any particular network interface or node.
