          Stateless Source Address Mapping for ICMPv6 Packets
                  draft-ietf-v6ops-ivi-icmp-address-06

Abstract

   A stateless IPv4/IPv6 translator may receive ICMPv6 packets
   containing non IPv4-translatable addresses as the source.  These
   packets should be passed across the translator as ICMP packets
   directed to the IPv4 destination.  This document presents
   recommendations for source address translation in ICMPv6 headers to
   handle such cases.

Internet-Draft      Source Address Mapping for ICMPv6     September 2012

1.  Introduction

   [RFC6145] section 5.2 of the "IP/ICMP Translation Algorithm"
   document. states that "the IPv6 addresses in the ICMPv6 header may
   not be IPv4-translatable addresses and there will be no corresponding
   IPv4 addresses representing this IPv6 address.  In this case, the
   translator can do stateful translation.  A mechanism by which the
   translator can instead do stateless translation is left for future
   work."  This document, Stateless Source Address Mapping for ICMPv6
   Packets, provides recommendations for this case.
