- 00:03:hardware type:link-layer address
- hardware type - 16 bit hardware type reserved by IANA. 1 means an Ethernet
device.
- link-layer address - The link layer address of a device generating the DUID.
4. Use Client Name to specify client's name. This is useful for logging or tracing only. It may be
up to 31 alphanumeric characters.
