Abstract

   This document specifies Multiple IPv4 - IPv6 address mapping
   encapsulation - fixed prefix (M46E-FP) specification.  M46E-FP makes
   backbone network to IPv6 only.  And also, M46E-FP can stack many IPv4
   networks, i.e. the networks using same IPv4 (private) addresses,
   without interdependence.

1.  Introduction

   This document provides Multiple IPv4 - IPv6 address maping
   encapsulation - fixed prefix (M46E-FP) specification.

   The basic strategy for IPv6 deployment is dual stack.  Viewing this
   strategy from operational side, operation cost of dual stack is
   higher than single stack operation.  Viewing from future, IPv6 only
   operation is more reasonable rather than IPv4 only operation.
   Therefore IPv6 only operation is desired.

   M46E-FP makes backbone network to IPv6 only and privide IPv4
   connectivities.  And also, M46E-FP can stack many IPv4 networks, i.e.
   the networks using same IPv4 (private) address, without
   interdependence.

2.  Architecture of M46E-FP

   IP address contain two information, one is locator information, and
   another is identifier information.  This is basic architecture of
   internet protocol, and also the Internet, and no difference between
