[ppml] Policy Proposal 2004-8: Allocation of IPv6 Address Space by the Internet Assigned Numbers Authority (IANA) Policy to Regional Internet Registries
Concerning the proposed policy, Allocation of IPv6 Address Space by the
Internet Assigned Numbers Authority (IANA) Policy to Regional Internet
Registries, which was posted to PPML on August 19, 2004, the ARIN Advisory
Council supports moving the proposed policy (as is) forward in the
ARIN welcomes feedback and discussion about this policy proposal in the
weeks leading to the ARIN Public Policy Meeting in Reston, Virginia
scheduled for October 20-21, 2004.
According to the ARIN Internet Resource Policy Evaluation Process the
Advisory Council will evaluate policy proposals after the Public Policy
Meeting. The feedback and discussion of policy proposals on the Public
Policy Mailing List will be included in the AC's evaluation.

Policy Proposal 2004-8: Allocation of IPv6 Address Space by the Internet
Assigned Numbers Authority (IANA) Policy to Regional Internet Registries
Author: John Sweeting
1. Minimum Allocation Size.
The minimum size of any allocation of IPv6 address space from IANA to an
RIR is prefix length /12. If this address space is not sufficient to meet
the needs of an RIR for a projected 18 month period, IANA shall allocate
to that RIR the address space for which it can provide justification.
2. Reservation of Unicast Address space.
2.1 IANA. By RFC 3513 the IANA has been allocated the range of IPv6
addresses beginning at binary value 001 (prefix length /3) for its
allocations of unicast address space. In order to support regional
aggregation of IPv6 address space IANA shall establish a reservation of a
prefix length of /6 from this space for each established RIR and for each
emerging RIR. Allocations to each RIR will be from the appropriate
2.2. RIRs. Each RIR may apply its own respective chosen allocation and
reservation strategy in order to meet the needs of its community and to
ensure the efficiency and efficacy of its work. Such reservations made by
an RIR will be considered as being allocated by that RIR when that RIR
applies for an allocation of address space from the IANA.
3. Initial Allocation.
3.1. Upon implementation of this policy IANA shall allocate to each
established RIR a /12 from the reservation established for each particular
3.2. Upon recognition of an RIR by ICANN that RIR shall receive a /12 from
the reservation set aside for that RIR.
4. Subsequent Allocation.
An RIR shall be eligible for an allocation of at least a minimal
allocation from the IANA when its current holdings are less than 50% of
its 18 month requirement or when it has less than 180 days of holdings
available. The IANA shall evaluate the requested allocation using a set
of administrative procedures that are mutually agreed to by the IANA and
the NRO. This set of procedures shall be enacted within 30 days of the
implentation of this policy.
5. Announcement of IANA allocations to the RIRs
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 IANA will make appropriate modifications to the "Internet Protocol V6
Address Space" page of the IANA website and may make announcements to only
its own global announcement lists. The IANA announcements will be limited
to which address ranges, the time of allocation and to which Registry they
have been allocated.
The current IANA allocation policy for IPv6 is an interim policy that was
promulgated in 1999. Operational experience has demonstrated the current
minimum allocation size is too small; that the built in reservation system
that must be followed by the RIRs does not allow for efficient and
effective management of the resource by the RIR; and does not provide for
an well known evaluation criteria. 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 between the NRO and ICANN.
