Abstract

   This document describes requirements for how IPv6 address prefixes

   should be delegated to an IPv6 subscriber's network (or "site").

1.  Introduction

   With the deployment of IPv6 [1], several Internet Service Providers

   are ready to offer IPv6 access to the public.  In conjunction with

   widely deployed "always on" media such as ADSL and the expectation

   that customers will be assigned a /48 IPv6 unicast address prefix

   (see RFC 3513 [3] and section 3 of RFC 3177 [2]), an efficient

   mechanism for delegating address prefixes to the customer's sites is

   needed.  The delegation mechanism will be intended to automate the

   process of informing the customer's networking equipment of the

   prefixes to be used at the customer's site.

   This document clarifies the requirements for IPv6 address prefix

   delegation from the ISP to the site.

2.  Scenario and terminology

   The following figure illustrates a likely example for the

   organization of a network providing subscription IPv6 service:
