Addressing

Regardless of what is happening at the upper layers, the IPX addressing scheme is an integral part of routing. NetWare is a software router. The routing table consists of unique internal (server) and external (wire) IPX numbers. The internal network number is internal to the file server and always ends in 0000.0000.0001. It is a logical network that routes packets to the physical networks to which a server is attached. Think of it like a loopback interface on a Cisco router. The external network number is the wire ID analogous to a subnet in IP. Periodic broadcasts are sent out on the wire, and the network and encapsulation numbers must match (as you saw in the chapter scenario).
