Internetwork Packet Exchange ('''IPX''') is the OSI-model Network Layer Protocol in the IPX/SPX Protocol Stack . The IPX/SPX protocol stack is supported by Novell 's NetWare Network Operating System . Because of Netware's popularity through the late 1980s into the mid 1990s , IPX became a popular Internetworking protocol. Novell derived IPX from Xerox Network Services ' IDP protocol. IPX usage is in general decline as the boom of the Internet has made TCP/IP nearly universal. Computers and networks can run multiple Network Protocol s, so almost all IPX sites will be running TCP/IP as well to allow for Internet connectivity. It is also now possible to run Novell products without IPX, as they have supported both IPX and TCP/IP since NetWare reached version 5. IPX ADDRESSING
Similarities with IP The IPX network address is conceptually identical to the network part of the IP Address (the parts with Netmask bits set to 1); the node address then has the same meaning as the bits of IP address with netmask bits set to 0. As the node address is usually identical to the MAC address of the network adapter, the Address Resolution Protocol is not needed. For Routing , the entries in the IPX Routing Table are similar to IP routing tables; routing is done by network address, and for each network address a network:node of the next router is specified in a similar fashion an IP address/netmask is specified in IP routing tables. IPX over Ethernet IPX can be transmitted over Ethernet using one of the following 4 encapsulation types:
