Only one zone name is assigned to a nonextended network; therefore, all nodes on that network belong to the same zone. On extended networks, each network range can be associated with up to 255 zones. When a network is associated with multiple zones, you configure the network with a zones list that contains the name of each zone. A node on an extended network can belong to only one zone in that list.
Each zones list has a default zone. When a node first starts up, it resides in the default zone. Each type of router can use its own method of defining which zone is the default zone. However, the routers on an internetwork must agree on which zone name is the default zone, and on the names in the zones list associated with that physical wire. Novell Internet Access Server 4.1 routing software uses the first zone in the list as the default zone. You can use NIASCFG to change the default.
Macintosh workstations belong to the default zone until the Macintosh user chooses another zone in the Network Control Panel. The zone in which a Macintosh workstation is registered is the zone in which its services, if any, are advertised. The Macintosh user can use the Chooser to view and access network services in any AppleTalk zone.
