Abstract

Mapping of IPv4 addresses in IPv6 addresses has been described in numerous mechanisms dating back to the mid-1990s [RFC1933] [RFC4213]. The "automatic tunneling" mechanism as first described in [RFC1933] assigned a globally unique IPv6 address to a host by combining the host's IPv4 address with a well-known IPv6 prefix. Given an IPv6 packet with a destination address with an embedded IPv4 address, a node could automatically tunnel this packet by extracting the IPv4 tunnel endpoint address from the IPv6 destination address.

          Mapping of Address and Port with Encapsulation (MAP-E)

Abstract

   This document describes a mechanism for transporting IPv4 packets    across an IPv6 network using IP encapsulation.  It also describes a    generic mechanism for mapping between IPv6 addresses and IPv4    addresses as well as transport-layer ports.
