AppleTalk Addressing 261
Figure 8-3 shows numbers by location. Cable ranges are allocated by building number and
floor. The Building 6 networks start with 6 and are followed by the floor number. So, network
6210 would be located in Building 6 on the second floor. By using known landmarks in the
number, it is less likely that the names will overlap. Numbering by location also helps you
administer future networks and isolate a faulty network.

Allocating Numbers by Location
Use Instantly Recognizable Names for Nodes
If resources have recognizable names, users can locate them more efficiently on the network. If
a simple convention for names exists, the user can quickly scan the list and identify a resource.
NBP provides the name-to-address resolution. Figure 8-4 shows an example of how nodes can
be identified by name. Users get the address from the name using the Chooser application and
NBP. A Network Visible Entity (NVE) is a 32-character string that helps AppleTalk define
devices on the AppleTalk network. To be an NVE, a device must have a network number, node
number, and socket number.
