prop-005-v004: Internet Assigned Numbers Authority (IANA) policy for
               allocation of IPv6 blocks to Regional Internet
               Registries
______________________________________________________________________


Proposed by:    APNIC Secretariat
                <secretariat@apnic.net>
Version:        004
Date:           2 September 2004


This document describes the policy governing the allocation of IPv6
address space from the IANA to the Regional Internet Registries (RIRs).
This document does not stipulate performance requirements in the
provision of services by IANA to an RIR in accordance with the policy.
Such requirements should be specified by appropriate agreements among
the RIRs and ICANN.


1.    Allocation principles
---------------------------

1.1  The unit of IPv6 allocation (and therefore the minimum IPv6
     allocation) from IANA to an RIR is a /12;

1.2  Every IPv6 allocation from IANA to an RIR will comprise a single
     CIDR prefix.

1.3  The IANA will allocate sufficient IPv6 address space to each RIR to
     support its registration needs for at least a 36 month period;

1.4  The IANA will allow each RIR to apply its own respective chosen
     allocation and reservation strategies in order to ensure the
     efficiency and efficacy of its work.


2.    IANA allocations to RIRs
------------------------------

2.1 Initial allocations

     On inception of this policy, each current RIR shall receive an IPv6 
     allocation from the IANA.

     Any new RIR shall, on recognition by ICANN, receive an IPv6 
     allocation from the IANA.


2.2  Additional allocations - Eligibility

     A RIR is eligible to receive additional IPv6 address space from the
     IANA when it has utilised (allocated or reserved) more than 50%
     of its total IPv6 address space holdings.

2.3  Size of additional allocations

     Each additional allocation to an RIR will be a number (one or more)
     of /12 blocks, sufficient to ensure that the RIR holds at least 36
     months' supply of IPv6 address space.


3.    Announcement of IANA allocations
--------------------------------------

When address space is allocated to a RIR, the IANA will send a detailed
announcement to the receiving RIR. The IANA will also make announcements
to all other RIRs, informing them of the recent allocation. The RIRs
will coordinate announcements to their respective membership lists and
any other lists they deem necessary.

The IANA will make appropriate modifications to the "Internet Protocol
V6 Address Space" page of the IANA website and may make announcements to
its own appropriate announcement lists.  The IANA announcements will be
limited to which address ranges, the time of allocation and to which
Registry they have been allocated.
