      Version 2 of prop-105 Distribution of returned IPv4 address
      (Modification of prop-088), reached consensus at the APNIC 36 Policy SIG
      and later at the APNIC Member Meeting.
      This proposal will now move to the next step in the APNIC Policy
      Development Process and is being returned to the Policy SIG mailing list
      for the final 8-week comment period.
      At the end of this period the Policy SIG Chairs will evaluate comments
      made and determine if the consensus reached at APNIC 36 still holds.
      If consensus holds, the Chairs of the Policy SIG will ask the Executive
      Council to endorse the proposal for implementation.
         - Send all comments and questions to: <sig-policy at apnic dot net>
         - Deadline for comments:  24:00 (UTC+10) Wednesday, 6 November 2013
      Proposal details
      This policy proposes to define a separate distribution
      policy for all non-103 IPv4 address blocks in the APNIC pool, to start
      the distributions once "Global policy for post exhaustion IPv4
      allocation mechanisms by the IANA" is activated.

      prop-105-v002: Distribution of returned IPv4 address blocks
                     (Modification of prop-088)
      Authors: Tomohiro Fujisaki fujisaki at syce dot net
               JP IPv4 address allocation discussion team
      1. Introduction
      After the final /8 policy is implemented, IPv4 address blocks received
      by APNIC are handled as being part of the final /8 pool and to
      redistribute these resources according to the final /8 policy
      (prop-088). This policy proposes to define a separate distribution
      policy for all non-103 IPv4 address blocks in the APNIC pool, to start
      the distributions once "Global policy for post exhaustion IPv4
      allocation mechanisms by the IANA" is activated.
      2. Summary
      While rapid implementation of IPv6 is in progress throughout the APNIC
      region, demands for IPv4 address still continue.
      In May 2012, the global policy  (Global Policy for Post Exhaustion: IPv4
      Allocation Mechanisms by the IANA) was ratified by ICANN board, and it
      will be implemented soon. Based on this policy, IPv4 address space
      returned to IANA will be distributed to RIRs, and its size is not
      expected to be so large but substantial enough to be able to consider an
      additional minimum allocation for APNIC members.
      APNIC is expected to have 6,917,683 (over /10) IPv4 addresses in its
      pool once the Global Policy is activated, as an re-allocation from IANA
      and IPv4 address space directly returned to APNIC from its members.
      Currently, these address blocks will be added to the reserve for
      distributions according to the final /8 policy, in addition to 103/8
      block already reserved for the purpose. Therefore, even if additional
      blocks are added in APNIC's pool while reserves remain in the 103/8
      block range, it is reserved for distribution under the final /8 policy.
      We propose to distribute this newly received address block and address
      blocks returned to APNIC to APNIC account holders.
      According to our survey conducted to the APNIC community, over 70% of
      the respondents expressed the needs to receive IPv4 address space,
      if a separate distribution policy is defined from the final /8 policy.
      3. Situation in other RIRs
      ARIN: no final /8 like policy.
      RIPE-NCC: similar /8 policy.
      4. Details
      Modify prop-088 to distribute non-103 IPv4 address blocks to APNIC
      account holders who meet the IPv4 distribution criteria define in APNIC
      If APNIC account holder, who was allocated an /22 from the final /8 pool,
      needs an additional IPv4 address block, they are eligible to receive
      another distribution of IPv4 block.
      The same policy as the final /8 policy will be applied in terms of the
      criteria and the size of the distribution given the requestor has
      utilized a total of /22 block from 103/8.
      This policy will be effective after allocation of returned IPv4 address
      blocks from IANA, based on "Global policy for post exhaustion IPv4
      allocation mechanisms by the IANA".
      The distribution policy for 103/8 block will remain unchanged, based on
      the final /8 policy.
      - Address size Consideration
      The current IPv4 Address size recovered by IANA from RIRs is
      18,204,416.  If this is equally distribute to 5 RIRs, APNIC is expected
      to receive 3,640,883 after the global policy is activated.
      APNIC also has a pool recovered directly from its account holders,
      with the total of 50 x 16s (max)*. By adding them up, APNIC is
      estimated to have 6,917,683 (over /10) IPv4 address after global
      policy will be activated.
       * Address blocks in ERX range need some coordination to distribute.
      APNIC has about 3,800 members, and about 4,800 members if NIR members
      is included. We can now distribute about 1,441 IPv4 address to all
      4,000 members, which is over /22.
      From the current final /8 address distribution trends, it will allow
      all LIRs who have received 103/22 to receive an additional /22 under
      this policy from the above IPv4 address pool (6,917,683) until
      - Subsequent IPv4 address re-allocated from IANA/returned to APNIC from
      its account holders
      If there are subsequent IPv4 address as described above, such IPv4
      address space will be pooled until:
       - Total IPv4 address size in APNIC pool will reach enough size which
         can distribute the maximum distribution size at at time
         (currently, /22 to a member)  to all APNIC members.
       - After the APNIC pool reaches the size sufficient to distribute to
         all APNIC members at that point in time, additional IPv4 address
         distribution will start from that pool.
      IANA pool size:
      5. Pros/Cons
      Advantages: Able to utilize non-103/8 address pool in APNIC for
      immediate distribution, instead of keeping as a reserve, in addition to
      Disadvantages: Some may feel the concern that adopting this policy
      discourages IPv6 deployment in the APNIC region. However, according to
      our survey, majority of the respondents responded revising the policy
      does not impact their IPv6 deployment plan.
      6. Effect on APNIC
      APNIC account holders can obtain one more IPv4 block of minimum
      allocation size as the upper limit (currently /22).
      7. Effect on NIRs
      NIRs can choose whether to implement this policy or not.
