 Basic support for IPv6 over IEEE Std 802.11 Networks operating Outside
        the Context of a Basic Service Set (IPv6-over-80211-OCB)
                draft-ietf-ipwave-ipv6-over-80211ocb-46

Abstract

   This document provides methods and settings, and describes
   limitations, for using IPv6 to communicate among nodes in range of
   one another over a single IEEE 802.11-OCB link with minimal change to
   existing stacks.  Optimizations and usage of IPv6 over more complex
   scenarios is not covered and is subject of future work.
