The ARIN Advisory Council (AC), acting under the provisions of the ARIN
Internet Resource Policy Evaluation Process (IRPEP), has reviewed policy
proposal 2004-8: Allocation of IPv6 Address Space by the Internet
Assigned Numbers Authority (IANA) Policy to Regional Internet Registries
and has determined that there is community consensus in favor of the
proposal to move it to last call. The AC made this determination at
their meeting at the conclusion of the ARIN Public Policy meeting in
April, 2005.  Minutes of the Public Policy Meeting can be found at
http://www.arin.net/meetings/minutes/ARIN_XV/index.html.  The results of
the AC meeting were reported by the Chair of the AC at the member
meeting.  This report can be found at

The policy proposal text is provided below and is also available at
http://www.arin.net/policy/proposals/2004_8.html.

Comments are encouraged.  All comments should be provided to
ppml at arin.net. This last call will expire at 12:00 Noon, Eastern Time,
June 1, 2005.

Policy Proposal 2004-8: Allocation of IPv6 Address Space by the Internet
Assigned Numbers Authority (IANA) Policy to Regional Internet Registries

Policy statement

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 this policy.
Such requirements will be specified by appropriate agreements between
ICANN and the NRO.

1. Allocation Principles

     * The unit of IPv6 allocation (and therefore the minimum IPv6
allocation) from IANA to an RIR is a /12
     * The IANA will allocate sufficient IPv6 address space to the RIRs
to support their registration needs for at least an 18 month period.
     * The IANA will allow for the RIRs to apply their own respective
chosen allocation and reservation strategies in order to ensure the
efficiency and efficacy of their work.

2. Initial Allocations

     * On inception of this policy, each current RIR with less than a
/12 unallocated address space, shall receive an IPv6 allocation from IANA
     * Any new RIR shall, on recognition by ICANN receive an IPv6
allocation from the IANA

3. Additional Allocations

A RIR is eligible to receive additional IPv6 address space from the IANA
when either of the following conditions are met.

     * The RIR's AVAILABLE SPACE of IPv6 addresses is less than 50% of a
/12.

     * The RIR's AVAILABLE SPACE of IPv6 addresses is less than its
established NECESSARY SPACE for the following 9 months.

In either case, IANA shall make a single IPv6 allocation, sufficient to
satisfy the established NECESSARY SPACE of the RIR for an 18 month period.

3.1 Calculation of AVAILABLE SPACE

The AVAILABLE SPACE of IPv6 addresses of a RIR shall be determined as
follows:

AVAILABLE SPACE = CURRENTLY FREE ADDRESSES + RESERVATIONS EXPIRING
DURING THE FOLLOWING 3 MONTHS - FRAGMENTED SPACE

FRAGMENTED SPACE is determined as the total amount of available blocks
smaller than the RIR's minimum allocation size within the RIR's
currently available stock.

3.2 Calculation of NECESSARY SPACE

If the applying Regional Internet Registry does not establish any
special needs for the period concerned, NECESSARY SPACE shall be
determined as follows:

NECESSARY SPACE = AVERAGE NUMBER OF ADDRESSES ALLOCATED MONTHLY DURING
THE PAST 6 MONTHS * LENGTH OF PERIOD IN MONTHS

If the applying RIR anticipates that due to certain special needs the
rate of allocation for the period concerned will be different from the
previous 6 months, it may determine its NECESSARY SPACE as follows:

Calculate NECESSARY SPACE as its total needs for that period according
to its projection and based on the special facts that justify these needs.

Submit a clear and detailed justification of the above mentioned
projection (Item A).

If the justification is based on the allocation tendency prepared by the
Regional Internet Registry, data explaining said tendency must be enclosed.

If the justification is based on the application of one or more of the
Regional Internet Registry's new allocation policies, an impact analysis
of the new policy/policies must be enclosed.

If the justification is based on external factors such as new
infrastructure, new services within the region, technological advances
or legal issues, the corresponding analysis must be enclosed together
with references to information sources that will allow verification of
the data.

If IANA does not have elements that clearly question the Regional
Internet Registry's projection, the special needs projected for the
following 18 months, indicated in Item A above, shall be considered valid.

4. Announcement of IANA Allocations

The IANA, the NRO, and the RIRs will make announcements and update their
respective web sites regarding an allocation made by the IANA to an RIR.
ICANN and the NRO will establish administrative procedures to manage
this process.
