IPX addressing

IPX addressing defines the internetwork, a collection of LANs connected by routers, bridges, and so forth.

IPX packet headers require both source and destination addresses. These designate the sender and the receiver of the packet respectively.

The IPX internetwork addressing scheme uses three address components shown in ``IPX internetwork address components'' (and which are described in more detail following).

IPX internetwork address components

Address	Byte Length	Description
Network	4 bytes	Identifies a specific network or LAN on an IPX internetwork
Node	6 bytes	Identifies individual nodes, or computers, on a network or LAN.
Socket	2 bytes	Identifies a process or function operating within a node. A socket is identified by a unique number
