Abstract

   This document specifies Multiple IPv4 - IPv6 mapping encapsulation -
   Prefix Translator (M46E-PT) specification.  M46E-PT expand IPv4
   network plane by connecting M46E-FP domain and M46E-PR domain.
   M46E-PT translate prefix part of M46E-FP address and M46E-PR address
   both are IPv6 address.  M46E-PT does not translate IPv4 packet which
   is encapsulated, so transparency of IPv4 packet is not broken.

1.  Introduction

   This document provide M46E Prefix Translator (M46E-PT) specification.

   The basic strategy for IPv6 deployment is dual stack.  However,
   because of exhaustion of IPv4 address, there will be no IPv4
   addresses for configuring dual stack in near future.  That means
   there will be IPv6 only networks automatically.

   However, there are many IPv4 only networks still exist and those
   seems continuous use in near future.  That means methods continuous
   use of IPv4 network over IPv6 only network will be required.

   M46E-FP [I-D.draft-matsuhira-m46e-fp] provide such methods.  In
   addition, M46E-PR [I-D.draft-matsuhira-m46e-pr] also provide such
