Multiple IPv4 - IPv6 mapped IPv6 address (M46A)

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.

Requirements Language

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].

Status of This Memo

This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet-Drafts is at https://datatracker.ietf.org/drafts/current/.

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

This Internet-Draft will expire on 6 October 2022.

Table of Contents

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.

 |      96 - m bits      |          m bits          |     32 bits  |
 +-----------------------+--------------------------+--------------+
 |      M46A prefix      |  IPv4 network plane ID   | IPv4 address |
 +-----------------------+--------------------------+--------------+
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

3. IANA Considerations

This document makes no request of IANA.

Note to RFC Editor: this section may be removed on publication as an RFC.
