         Multiple IPv4 - IPv6 address mapping translator (M46T)
                        draft-matsuhira-m46t-02

Abstract

   This document specifies Multiple IPv4 - IPv6 address mapping
   Translator (M46T) specification.  M46T enable access to IPv4 only
   host from IPv6 host.  IPv4 host is identified as M46 address in IPv6
   address space.  The address assigned to IPv4 host may be global IPv4
   address or private IPv4 address.  M46T does not support access to
   IPv6 host from IPv4 only host.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
