Definition of the UUID-Based DHCPv6 Unique Identifier

Overview

RFC 6355, “Definition of the UUID-Based DHCPv6 Unique Identifier”, is a Proposed Standard document published in August 2011 by T. Narten, J. Johnson. The canonical text is published by the RFC Editor.

Abstract

This document defines a new DHCPv6 Unique Identifier (DUID) type called DUID-UUID. DUID-UUIDs are derived from the already-standardized Universally Unique IDentifier (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. [STANDARDS-TRACK]
