AppleTalk Phase 2 Routing Service
Assigning AppleTalk Addresses
Assigning AppleTalk Addresses
In an AppleTalk internet, nodes (end systems or routers) and networks are
assigned addresses. Nodes and routers are each assigned node addresses
that are unique throughout the internet.
The AppleTalk node address consists of:
a 16-bit network number (1–65279)
an 8-bit node identifier (1–253)
Each end node is assigned to an AppleTalk network and has a unique node
identifier. Each AppleTalk network is assigned a range of network numbers.
There can be up to 253 nodes for each number in the network number range.
Each network number range must be unique and must not overlap.
This network number range is configured by the user on at least one of the
routers residing on the network. That router is called the seed router for that
network. The AppleTalk nodes dynamically determine the network number
portion of their node address. If the node is being restarted, and there is a
network number stored in non-volatile memory, that number will be used. If
not, a network number will be chosen from the startup range configured by
the user on the seed router, which is discussed in more detail below.
The node identifier portion of the node address is assigned by the AppleTalk
software automatically.
