Abstract

This document obsoletes RFC 2374, "An IPv6 Aggregatable Global Unicast Address Format". It defined an IPv6 address allocation structure that includes Top Level Aggregator (TLA) and Next Level Aggregator (NLA). This document makes RFC 2374 and the TLA/NLA structure historic.

Abstract

� � This document obsoletes RFC 2374, "An IPv6 Aggregatable Global

� � Unicast Address Format".� It defined an IPv6 address allocation

� � structure that includes Top Level Aggregator (TLA) and Next Level

� � Aggregator (NLA).� This document makes RFC 2374 and the TLA/NLA

� � structure historic.

1.� Introduction

� � RFC 2374, "An IPv6 Aggregatable Global Unicast Address Format",

� � defined an IPv6 address allocation structure that includes TLA and

� � NLA.� This document replaces RFC 2374, and makes RFC 2374 and the

� � TLA/NLA structure historic.

2.� TLA/NLA Made Historic

� � The TLA/NLA scheme has been replaced by a coordinated allocation

� � policy defined by the Regional Internet Registries (RIRs) [IPV6RIR].

� � Part of the motivation for obsoleting the TLA/NLA structure is

� � technical; for instance, there is concern that TLA/NLA is not the

� � technically best approach at this stage of the deployment of IPv6.

� � Moreover, the allocation of IPv6 addresses is related to policy and

� � to the stewardship of the IP address space and routing table size,

� � which the RIRs have been managing for IPv4.� It is likely that the

� � RIRs' policy will evolve as IPv6 deployment proceeds.

� � The IETF has provided technical input to the RIRs (for example,

� � RFC 2374 was the definition of addresses for Format Prefix 001
