[sig-policy] prop-051: Global policy for the allocation of the remaining
The proposal "Global policy for the allocation of the remaining IPv4
address space" has been sent to the Policy SIG for review. It will be
presented at the Policy SIG at APNIC 24 in New Delhi, India, 29 August
- 7 September 2007.
I invite you all to review the proposal below and send comments to the
mailing list before APNIC 24.

1. Introduction
----------------
In order to assure the equal distribution of the IPv4 address space
across RIR regions, this policy proposal describes a process for the
allocation of the remaining IPv4 space from IANA to the existing RIRs.
2. Summary of current problem
------------------------------
The IANA pool is decreasing rapidly. The current "on demand" policy
in a way rewards who uses the most addresses and maintaining. As more
addresses are allocated, a rush to monopolize the allocation of
addresses from IANA is possible.
3. Situation in other RIRs
----------------------------
LACNIC: This proposal reached consensus at LACNIC X meeting and is
awaiting Board approval.
AFRINIC/RIPE/ARIN: The prooposal proposal is being submitted to all
regions.
4. Details of the proposal
----------------------------
Policy Statement:
This policy describes the process for the allocation of the remaining
IPv4 space from IANA to the RIRs. When a minimum amount of available
space is reached, an identical number of IPv4 allocation units (/8s)
will be allocated from IANA to each RIR, replacing the current IPv4
allocation policy.
In order to fulfill the requirements of this policy, at the time it is
adopted, an identical number of IPv4 allocation units (N units) will be
reserved by IANA for each RIR. The number N is defined as: 5. The
reserved allocation units will no longer be part of the available space
at the IANA pool. The process for the allocation of the remaining IPv4
space is divided in two consecutives phases:
1. Existing policy phase:
During this phase IANA will continue allocating IPv4 addresses to
the RIRs using the existing allocation policy. This phase will
continue until a request for IPv4 address space from any RIR to
IANA cannot be fulfilled with the remaining IPv4 space available at
the IANA pool.
This will be the last IPv4 address space request that IANA will
accept from any RIR. At this point the next phase of the process
will be initiated.
2. Exhaustion phase:
IANA will automatically allocate the reserved IPv4 allocation units
to each RIR (N units to each one) and respond to the last request
with the remaining available allocation units at the IANA pool (M
units).
2.1. Size of the final IPv4 allocations:
During this phase IANA will automatically allocate N allocation
units to each RIR from the reserved space defined in this
policy. IANA will also allocate M allocation units to the RIR
that submitted the last request for IPv4 addresses.
2.2. Allocation of the remaining IPv4 Address space:
After the completion of the evaluation of the final request for
IPv4 addresses, IANA must:
A) Immediately notify the NRO about the activation of the
second phase of this policy.
B) Proceed to allocate M allocation units to the RIR that
submitted the last request for IPv4 address space.
C) Proceed to allocate N allocation units to each RIR from the
reserved space.
5. Advantages and disadvantages of the proposal
-------------------------------------------------
Advantages:
- It eliminates the pressure on the central pool.
- It allows each RIR to approve new policies for the allocation of
their remaining space.
- It allows the discussion of the concept of the policy first and the
size of the final allocation later.
Disadvantage:
- Concerns have been raised regarding the address blocks that will be
kept at smaller RIRs (particularly LACNIC and AFRINIC). However,
at the actual address consumption rate, to open those blocks
(10 x /8) would only represent a 12-month extension of the
exhaustion date for the bigger RIRs.
6. Effect on APNIC members
----------------------------
APNIC will continue receiving IPv4 allocation units by the current
policy until the central pool reachs 25 x /8. At that time APNIC and
the rest of the RIR will receive its last 5 x /8.
7. Effect on NIRs
-------------------
No effect.
