*** Last Call: Policy Proposal 2003-12: IANA to RIR Allocation
of IPv4 Address Space ***

IANA to RIR Allocation of IPv4 Address Space

This document describes the policies governing the
allocation of IPv4 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 these
policies. Such requirements should be specified by
appropriate agreements among the RIRs and ICANN.

1. Allocation Principles

     - The IANA will allocate IPv4 address space to the RIRs
     in /8 units.
     
     - The IANA will allocate sufficient IPv4 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

Each new RIR shall, at the moment of recognition, be
allocated a new /8 by the IANA. This allocation will be made
regardless of the newly formed RIR's projected utilization
figures and shall be independent of the IPv4 address space
that may have been transferred to the new RIR by the already
existing RIRs as part of the formal transition process.

3. Additional Allocations

A RIR is eligible to receive additional IPv4 address space
from the IANA when either of the following conditions are
met.

     - The RIR's AVAILABLE SPACE of IPv4 addresses is less
     than 50% of a /8 block.
     
     - The RIR's AVAILABLE SPACE of IPv4 addresses is less
     than its established NECESSARY SPACE for the following
     9 months.

In either case, IANA shall make a single allocation of a
whole number of /8 blocks, 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 IPv4 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 greater than the previous 6 months, it may determine
its NECESSARY SPACE as follows:

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

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 V4 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.

Public Policy Mailing List Discussion Summary

There were two posts on PPML regarding this proposal; the
three following paragraphs are from that discussion.

     This is a global policy proposal to define the policies
     under which the IANA will allocate IPv4 address space
     to the Regional Internet Registries (RIR).
     
     It has already appeared on the public policy agendas of
     the APNIC and RIPE NCC meetings.  This policy proposal
     will also be discussed at the next LACNIC public policy
     meeting.
     
     Following discussion in all four regions, the proposal
     and discussion results will be forwarded to the ICANN
     ASO Address Council for review and submittal to the
     ICANN Board, as it is considered a global policy
     proposal.
