Node Addresses

In a ZigBee network, each node must have unique identification. This is achieved by means of two addresses:

IEEE address
Network address

These are described below.

IEEE Address

This is a 64-bit address, allocated by the IEEE, which uniquely identifies the device – no two devices in the world can have the same IEEE address. It is also called the MAC address or the extended address.

Network Address

This is a 16-bit address identifies the node in the network - it is local to that network (thus, two nodes on separate networks may have the same network address). Network addresses are allocated by the parent node (Router or Co-ordinator) when a node joins a network. It is also called the short address.

The Co-ordinator always takes the network address 0x0000.
