Description: Each entry specifies an IPX network number, assigns it to a port, and specifies the header format to be used when sending IPX packets to that network. On Ethernet ports, up to four different IPX Network Numbers may be specified, of which only one may be primary. On serial ports, only one IPX Network Number may be configured. The header format assigned to a serial port is irrelevant. The header format is determined, instead, by the owner of the port (X25, ppp, etc.)

If an attached network number is removed, the server entries that are reachable through that network will be removed. All routing entries that are reachable through that network are removed as well.
