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

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].¶
Figure 1 shows M46A architecture.¶
