In my capacity as a member of the ASO Address Council appointed
by the AfriNIC Board, and in terms of my responsibilities as
recorded in clause 2 of attachment A of the ICANN ASO Mou
(http://nro.icann.org/docs/aso-mou2004.html), I hereby submit the
appended proposal in terms of the AfriNIC policy development process
(http://www.afrinic.net/pdp.htm), and request that this proposal be
placed on the agenda of the next AfriNIC open policy meeting.
This is a proposed global policy, which is intended to
be handled in terms of attachment A of the ICANN ASO MoU

AfriNIC Proposed policy:
Allocation of IPv6 Address Space by the Internet Assigned
Numbers Authority (IANA) to Regional Internet Registries
Submitted by: A P Barrett
Date: 1 August 2005
Related policies and proposals in other regions:
Note: The wording below is identical to the wording of ARIN policy
2004-8. Some of the other RIRs are considering proposals with
similar but not identical wording.
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
3.1 Calculation of AVAILABLE SPACE
The AVAILABLE SPACE of IPv6 addresses of a RIR shall be determined as
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
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
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
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
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.
