      A Unified Stateful/Stateless Configuration Service for IPv6
                 draft-templin-6man-dhcpv6-ndopt-08.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), while the Dynamic Host Configuration
   Protocol for IPv6 (DHCPv6) specifies a separate stateful service.
   This document presents IPv6ND extensions for providing a unified
   stateful/stateless configuration service.
