1.  Introduction

   This document provides Multiple IPv4 address and port number - IPv6
   address mapping encapulation (M4P6E) base specification.

   M4P6E provide IPv4 address sharing function without Network Address
   Translation (NAT [RFC1631]).  M4P6E require IPv6 network.

2.  Architecture of M4P6E

   Figure 1 shows M4P6E address architecture.  M4P6E address consists
   four parts, M4P6E prefix, IPv4 network plane ID, IPv4 address, and
   Port number.
