| 1.6.3 | Novell IPX addressing
Novell IPX addressing uses a two-part address, the network number and the node number. The IPX network number can be up to 8 hexadecimal digits in length. Usually, only the significant digits are listed. This number is assigned by the network administrator. The example features the IPX network 4a1d and 3f. The IPX node number is 12 hexadecimal digits in length. This number is usually the MAC address obtained from a network interface that has a MAC address. The example features the IPX node 0000.0c56.de33 on the 4a1d network. Another node address is 0000.0c56.de34 on the 3f. Each interface retains its own address. The use of the MAC address in the logical IPX address eliminates the need for an Address Resolution Protocol (ARP).
