Figure 2-3. IPX Address Format
Network identifies a network, typically a LAN, within an internetwork. The
network address of the NonStop system is obtained from a
NetWare file server when the NonStop IPX/SPX subsystem is
started.
Note. On a NetWare LAN, IPX network addresses are assigned only to NetWare file servers
and dedicated routers and bridges. The NonStop IPX/SPX subsystem uses the IPX NetWare
address of the first NetWare file server that replies to its broadcast for a network address.
