Multiple IPv4 - IPv6 mapped IPv6 address (M46A)
draft-matsuhira-m46a-07
Abstract
This document specifies Multiple IPv4 - IPv6 mapped IPv6
address(M46A) spefification. M46A is IPv4 mapped IPv6 address with
plane ID. Unique allocation of plane id value enable IPv4 private
address unique in IPv6 address space. This address may use IPv4 over
IPv6 encapsulation and IPv4 - IPv6 translation.

Internet-Draft M46A December 2019
1. Introduction
This document specifies Multiple IPv4 - IPv6 mapped IPv6
address(M46A) spefification. M46A is IPv4 mapped IPv6 address with
plane ID. Unique allocation of plane ID value enable IPv4 private
address unique in IPv6 address space.
This address may use IPv4 over IPv6 encapsulation such as Multiple
IPv4 - IPv6 mapping encapsulation - fixed prefix (M46E-FP) M46E-FP
[I-D.draft-matsuhira-m46e-fp], Multiple IPv4 - IPv6 mapping
encapsulation - prefix resolution (M46E-PR)M46E-PR
[I-D.draft-matsuhira-m46e-pr], Multiple IPv4 - IPv6 mapping
encapsuration - prefix translator (M46E-PT)M46E-PT
[I-D.draft-matsuhira-m46e-pt] and IPv4 - IPv6 translation such as
Multiple IPv4 - IPv6 mapping translator (M46T)M46T
[I-D.draft-matsuhira-m46t].
2. M46A architecture
Figure 1 shows M46A architecture.

Figure 1
M46A consists of three parts as follows.
M46A prefix
M46A prefix. This value is fixed value with M46E-FP, and non
fixed value with M46E-PR.
IPv4 network plane ID
IPv4 network plane ID is network identification of IPv4 network
plane.
IPv4 address
IPv4 address
