In general IPX/SPX is a protocol stack that is supported by the Novell Netware operating systems. It does not require to establish or maintain the connection before the communication starts between the network computers. IPX doesn’t take the unnecessary network resources.
Today computers are networks can support multiple communication protocols. Novell computers support TCP/IP and TCP/IP computers support Novell Netware.
Today a computer network can be heterogeneous i.e. it can be mixture of multiple logical and physical networks. IPX addressing now has been replaced by the TCP/IP. It was previously used for the network games.
