NamingSystem: ZigBee Address as a device identifier

Official URL: http://terminology.hl7.org/NamingSystem/zigbee-address-identifier				Version: 1.0.0
Active as of 2021-06-14			Responsible: IHE Patient Care Devices (PCD)	Computable Name: ZigBee_Address_Identifier

The ZigBee Address is a unique 64-bit identifier assigned to each ZigBee device by the manufacturer. ZigBee Addresses are usually displayed as 8 bytes written in hexadecimal and separated by colons (example - DF:3B:00:11:22:33:FF:EE). They are an essential part of ZigBee-based protocols. The most-significant 24 bits of the ZigBee address is the so-called Organizationally Unique Identifier (OUI). It can be used to determine the manufacturer of a device. OUI prefixes are assigned by the Institute of Electrical and Electronics Engineers (IEEE). An EUI (Extended Unique Identifier) is generally made from an OUI and thus a ZigBee Address is also an EUI-64. When a ZigBee device joins a network it is assigned an additional 16-bit address sometimes referred to as its network address. This address is different from the 64-bit ZigBee address and is dynamic.
