Multiple IPv4 - IPv6 address mapping encapsulation - fixed prefix
(M46E-FP)
draft-matsuhira-m46e-fp-07
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.

Internet-Draft M46E-FP December 2019
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
