Abstract

This document defines an IPv6 provider-based unicast address format for use in the Internet. The address format defined in this document is consistent with the "IPv6 Addressing Architecture" [ARCH] and the "An Architecture for IPv6 Unicast Address Allocation" [ALLOC], and is intended to facilitate scalable Internet routing.

An IPv6 Provider-Based Unicast Address Format

Status of this Memo

This document specifies an Internet standards track protocol for the

Internet community, and requests discussion and suggestions for

improvements. Please refer to the current edition of the "Internet

Official Protocol Standards" (STD 1) for the standardization state

and status of this protocol. Distribution of this memo is unlimited.

1.0 Introduction

This document defines an IPv6 provider-based unicast address format

for use in the Internet. The address format defined in this document

is consistent with the "IPv6 Addressing Architecture" [ARCH] and the

"An Architecture for IPv6 Unicast Address Allocation" [ALLOC], and is

intended to facilitate scalable Internet routing.

The unicast address format defined in this document doesn't preclude

the use of other unicast address formats.

2.0 Overview of the IPv6 Address

IPv6 addresses are 128-bit identifiers for interfaces and sets of

interfaces. There are three types of addresses: Unicast, Anycast,

and Multicast. This document defines a specific type of Unicast

address.

In this document, fields in addresses are given specific names, for

example "subscriber". When this name is used with the term "ID" (for

"identifier") after the name (e.g., "subscriber ID"), it refers to

the contents of the named field. When it is used with the term

"prefix" (e.g., "subscriber prefix") it refers to all of the address

up to and including this field.

The specific type of an IPv6 address is indicated by the leading bits

in the address. The variable-length field comprising these leading

bits is called the Format Prefix (FP).

This document defines an address format for the 010 (binary) Format

Prefix for Provider-Based Unicast addresses. The same address format

could be used for other Format Prefixes, as long as these Format

Prefixes also identify IPv6 unicast addresses. Only the "010" Format

Prefix is defined here.
