This document defines a new DHCPv6 Unique Identifier (DUID) type, called DUID-UUID. DUID-UUIDs are derived from the already standardized UUID format. DUID-UUID makes it possible for devices to use UUIDs to identify themselves to DHC servers and vice versa. UUIDs are globally unique and readily available on many systems, making them convenient identifiers to leverage within DHCP.
