Abstract

   This document provides recommendations to the addressing registries
   (APNIC, ARIN and RIPE-NCC) on policies for assigning IPv6 address
   blocks to end sites.  In particular, it recommends the assignment of
   /48 in the general case, /64 when it is known that one and only one
   subnet is needed and /128 when it is absolutely known that one and
   only one device is connecting.

   The original recommendations were made in an IAB/IESG statement
   mailed to the registries on September 1, 2000.  This document refines
   the original recommendation and documents it for the historical
   record.

1. Introduction

   There have been many discussions between IETF and RIR experts on the
   topic of IPv6 address allocation policy.  This memo addresses the
   issue of the boundary in between the public and the private topology
   in the Internet, that is, how much address space should an ISP
   allocate to homes, small and large enterprises, mobile networks and
   transient customers.

   This document does not address the issue of the other boundaries in
   the public topology, that is, between the RIRs and the LIRs.

   This document was developed by the IPv6 Directorate, IAB and IESG,
   and is a recommendation from the IAB and IESG to the RIRs.
