Dear
SIG members The
proposal 'Ensuring efficient use of historical IPv4 resources' has been sent to
the Policy SIG for review. It will be presented at the Policy SIG at APNIC The
proposal's history can be found at:
http://www.apnic.net/policy/proposals/prop-066-v001.html We
invite you to review and comment on the proposal on the mailing list before the
meeting. The
comment period on the mailing list before an APNIC meeting is an important part
of the policy development process. We encourage you to express your views on
the proposal:
- Do you support or oppose this proposal?
- Does this proposal solve a problem you are experiencing? If so,
tell the community about your situation.
- Do you see any disadvantages in this proposal?
- Is there anything in the proposal that is not clear?
- What changes could be made to this proposal to make it more
effective? Randy

Introduction ---------------- This
is a proposal to include all historical address allocations when assessing a
network's eligibility for more IPv4 addresses. 2.
Summary of current problem ------------------------------ The
unallocated pool of IPv4 addresses is predicted to run out within the next few
years. As the unallocated pool dwindles, it is important to ensure that
the remaining IPv4 addresses are allocated responsibly and fairly. Currently,
when LIRs apply for new IPv4 allocations from APNIC, they only have to include
the past allocations they have received from APNIC as part of the documentation
and justification process. They do not have to declare any historical addresses
[1] they may have received prior to receiving address space from APNIC. As
a result of this, there is a large amount of historical IPv4 address space
where little or nothing is known about its use. At
the moment LIRs can receive more scarce IPv4 address space from APNIC while at
the same time hoarding unused historical address space. This uses up the
remaining IPv4 pool more rapidly than is really necessary. 3.
Situation in other RIRs --------------------------- The
other RIRs do not currently include historical allocations when assessing
requests for allocations from the RIR pools. This
proposal has not been submitted to any other region. 4.
Details of the proposal --------------------------- This
is a proposal to modify the criteria for receiving IPv4 address space so that
both historical addresses and previous allocations are included.
- This proposal applies to all historical IPv4 resources
registered in the APNIC Whois Database.
- Historical IPv4 resources that are not managed under the
existing historical maintenance or transfer policies will remain
free of fees. 5.
Advantages and disadvantages of the proposal ------------------------------------------------ 5.1
Advantages
- Ensures that organisations are using scarce IPv4 address space
resources to the fullest extent possible.
- The utilisation of historical IPv4 addresses will be brought
into line with current best practices for address management.
- The remaining IPv4 free pool will be delegated to LIRs that have
a genuine need for IP addresses. 5.2
Disadvantages
- Organisations can no longer hoard unused address space while at
the same time receive more scarce address space from APNIC's
pool.
- LIRs with historical IPv4 addresses may find it time consuming
to change network architecture that uses historical IPv4
addresses in an inefficient manner.
However, the difficulties felt by these networks is outweighed
by the greater benefits of ensuring that the remaining IPv4
address space is delegated to networks with a genuine need for
IPv4 allocations. 6.
Effect on APNIC members --------------------------- APNIC
members who have applied best practices for address space management for all
their address ranges will not be affected. APNIC
members who have not applied best practices for all their address ranges may
need to modify their management of historical addresses before they can qualify
for IPv4 addresses from APNIC. There
will be no impact on fees paid by members. 7.
Effect on NIRs ------------------ The
proposal has no direct impact on NIRS, but impacts members of NIRs in the same
way it impacts APNIC members. 8.
