    A Unified Stateful/Stateless Autoconfiguration Service for IPv6
                 draft-templin-6man-dhcpv6-ndopt-06.txt

Abstract

   IPv6 Neighbor Discovery (IPv6ND) specifies a control message set for
   nodes to discover neighbors, routers, prefixes and other services on
   the link.  It also supports a manner of StateLess Address
   AutoConfiguration (SLAAC).  The Dynamic Host Configuration Protocol
   for IPv6 (DHCPv6) specifies a separate stateful autoconfiguration
   service.  This document presents IPv6ND extensions for providing a
   unified stateful/stateless autoconfiguration service.

1.  Introduction

   IPv6 Neighbor Discovery (IPv6ND) [RFC4861] specifies a control
   message set for nodes to discover neighbors, routers, prefixes and
   other services on the link.  It also supports a manner of StateLess
   Address AutoConfiguration (SLAAC).  The Dynamic Host Configuration
   Protocol for IPv6 (DHCPv6) specifies a separate service for
   delegation of prefixes, addresses and any other stateful information
   [RFC3315][RFC3633].  This document presents IPv6ND extensions for
