    • Dear SIG members,
      The proposal, 'Distribution of IPv4 addresses once the final /8 period
      starts', has been sent to the Policy SIG for review. It will be
      presented at the Policy SIG at APNIC 29 in Kuala Lumpur, 21-25 February
      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

      Version:   1

      1.  Introduction
      This is a proposal to handle any IPv4 address space received by APNIC
      after the final /8 policy is implemented as being part of the final /8
      pool and to redistribute these resources according to the final /8
      2.  Summary of current problem
      After APNIC has activated the "final /8" allocation policies[1], there
      is the possibility that APNIC will receive further IPv4 addresses.
      These IPv4 addresses will come either directly from Asia Pacific
      networks that no longer need them, or, if the global policy proposal
      for redistributing resources from the IANA succeeds, from the IANA.
      The intent of the authors of the original final /8 policy proposal was
      to have all other IPv4 allocation and assignment policies replaced by
      the delegation policy described in the final /8 policy. However, the
      current language of the final /8 policy does not explicitly repeal the
      other IPv4 allocation and assignment policies. The authors are therefore
      aware that there may be some confusion as to how such returned addresses
      should be distributed by APNIC. This proposal seeks to clarify the
      3.  Situation in other RIRs
      There is no similar policy or proposal in other regions.
      4.  Details of the proposal
      It is proposed that:
      4.1 When APNIC has distributed all other available IPv4 resources, and
           has to start distributing from the final /8, any IPv4 resources
           received after that point will be placed into the final /8 pool.
           - This placement into the final /8 pool will occur even if the
             result is a pool larger than one /8.
           - Subject to any future global policy for the redistribution of
             addresses received by the IANA from the RIRs (for example,
             prop-069), this placement applies to any IPv4 addresses APNIC
             receives from:
              - the IANA; and/or
              - holders of addresses in the APNIC Whois Database
      4.2 These resources received in 4.1 are to be distributed according to
           the same policies as apply to the final /8 [1].
      5.  Advantages and disadvantages of the proposal
      5.1 Advantages
           - It reduces confusion possible if IPv4 resources are received
             outside the final /8 but during the period when the final /8
             policy is active by explicitly stating how these IPv4 resources
             are to be handled.
      5.2 Disadvantages
           - No disadvantages are foreseen.
      6.  Effect on APNIC members
      APNIC members can only request and receive a single distribution from
      the final /8.  This would also apply to any other IPv4 addresses
      placed in the final /8 pool by this policy.
      7.  Effect on NIRs
      This will affect NIR members in the same way as APNIC members.
