IPX/SPX
The IPX (Internetwork Packet Exchange/SPX(Sequenced Packet Exchange) protocols were developed by Novell and were used with Novell Netware operating systems to route packets in within a network. IPX is a connectionless datagram-based network protocol and it is the fastest routable protocol, whereas SPX is connection oriented.
Novell IPX network addresses are unique and are represented in hexadecimal format that consist of two parts:
- Network number.
- Node number.
The IPX network number is 32 bits long. The node number, generally the Media Access Control (MAC) address for one of the system's network interface cards is 48 bits long.
