[sig-policy] prop-046-v002: IPv4 countdown policy proposal
Dear SIG members
Version two of the proposal "IPv4 countdown policy proposal"
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.
The proposal's history can be found at:

Version: 2
Date: 6 August 2007
1. Introduction
----------------
The exhaustion of IPv4 address space is projected to take place within
the next few years. This proposal seeks to focus on measures that should
be taken globally in the address management area in order to prepare for
the situation in all RIR regions. Policy measures that require
considerations within the Asia Pacific region are reviewed in a separate
discussions paper.
2. Summary of current problem
------------------------------
1) Continue applying a global coordinated policy for distribution of the
last piece(s) of RIR's unallocated address block does not match the
reality of the situation in each RIR region.
Issues each RIR region will face during the exhaustion period
vary by
region as the level of development of IPv4 and IPv6 are widely
different. As a result, applying a global co-ordinated policy may
not
adequately address issues in a certain region while it could be work
for the others.
For example, in a region where late comers desperately need even
small blocks of IPv4 addresses to access to the IPv4 Internet, a
policy that defines the target of allocations/assignments of IPv4
address space to be late comers would be appropriate in such region.
This would allow availablilty of IPv4 address space for such
requirements for more years.
Another example comes from difference in IPv6 deployment rate.
For a region where IPv6 deployment rate is low, measures may be
necessary to prolong IPv4 address life for the existing business as
well as for new businesses until networks are IPv6 ready. Some
regions may have strong needs to secure IPv4 address space for
translators.
A globally coordinated policy which addresses all the issues listed
above to meet the needs for all RIR regions may result in not
solving
issues in any of the regions.
2) LIRs and stakeholders remain unprepared for the situation if they are
not informed.
If LIRs and the community are uninformed of the exhaustion, their
services and networks remain unprepared to face the situation at the
time of exhaustion.
3. Situation in other RIRs
----------------------------
Version 1 of this proposal has been submitted to all RIRs for
discussion. This version of the proposal, version 2, will also be
submitted to all RIRs.
4. Details of the proposal
----------------------------
This proposal seeks to provide the following solutions to the
problems listed above.
1) RIR community should be able to define their own regional policies on
how to assign the last piece(s) of allocation block in order to
address their own regional issues during the exhaustion period.
2) RIRs should provide official projection of the date when LIRs will be
able to receive the allocations under the current criteria. The
criteria should remain consistent until this date in order to avoid
confusion.
The details of the proposal is as follows:
1) It should be completely left up to each RIR communities to define a
regional policy on how to distribute the remaining RIR free pool to
LIRs within their respective regions after "IANA Exhaustion Date".
- This will lead to solution 1)
- A policy during the exhaustion period within the AP region is
discussed a separate discussion paper
Note 1: It is fine for an RIR to continue operations with the
existing policy if that is the consensus decision of the
respective RIR community.
Note 2: Address recovery and re-distribution of recovered address
space is another important measure for considerations, but
should be treated as a separate policy proposal from
distribution of new IANA pool.
2) Distribute a single /8 to each RIR at the point when new IANA free
pool hits 5 */8. This date is defined as "IANA Exhaustion Date".
- This will lead to solution 1)
- A single /8 is the minimum practical size of allocation from IANA
to RIRs although smaller size is theoretically possible
- Larger allocation size is not desirable as it artificially
fastens the exhaustion date of certain regions
3) RIRs should provide an official projection on IANA Exhaustion Date
to the community through their website, at their Policy Meetings
and through any other effective means.
- This will lead to solution 2)
- Although reliable projections by personal efforts are currently
available, official projections provided RIRs help raise
community awareness as well as helps ISP staff to convince their
organization to prepare for the situation as a reliable source of
information.
4) RIRs should maintain the current address distribution criteria until
the date defined as "IANA Exhaustion Date".
- This will lead to solution 2)
5. Advantages and disadvantages of the proposal
-------------------------------------------------
Advantages:
- It allows each RIR community to define a policy on how to distribute
the last piece(s) of allocations which best matches their situation.
- It helps LIR be better informed of the date when they are able to
receive allocations from RIRs under the current criteria and
prepare for the event.
Disadvantages:
- Concerns could be raised about allocating a fixed size to all RIRs,
that it artificially fastens the consumption rate of some RIR
regions.
However, its impact is kept to minimum by keeping the allocation size
to a single /8 which makes merely 3-4 months difference.
- Concerns could be raised that explicitly allowing regional policies
will encourage RIR shopping. However, this should not happen if the
requirements within each region is adequately reflected in each RIR's
policy through PDP. RIR may also chose to add criteria to prevent
LIRs
from other regions submitting such requests.
6. Effect on APNIC members
----------------------------
APNIC members will be able to define a policy on how to distribute the
last piece(s) of allocations which best matches the situation in AP
region.
APNIC members will be better informed of the date when they are able to
receive allocations from APNIC under the current criteria, through
official information provided by APNIC/RIRs.
7. Effect on NIRs
-------------------
The effect on APNIC members applies to members of NIRs. NIRs are
therefore expected to inform their communities of the situation.
8. Additional reference
-----------------------
This proposal should be read in conjunction with a discussion paper
which reviews RIR to LIR allocation regional policy after the IANA
exhaustion date in Asia Pacific region.
