    • Dear SIG members,

      The proposal "prop-127-v001: Change maximum delegation size of 103/8
      IPv4 address pool to a /23" has been sent to the Policy SIG for review.

      It will be presented at the Open Policy Meeting at APNIC 47 in
      Daejeon, South Korea on Wednesday, 27 February 2019.

      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?

      prop-127-v001: Change maximum delegation size of 103/8 IPv4 address
      pool to a /23

      1. Problem Statement

      This is a proposal to change the maximum size of IPv4 address delegations
      from the APNIC 103/8 IPv4 address pool [1] to a /23.

      2. Objective of policy change

      The current final /8 allocation policy[1] requires that the current minimum
      delegation size for IPv4 is a /24 and each APNIC account holder is only
      eligible
      to receive IPv4 address delegations totalling a maximum /22 from the
      APNIC 103/8
      IPv4 address pool.

      According to the APNIC IPv4 Address Report, https://ipv4.potaroo.net/,
      remaining
      addresses in the APNIC 103/8 pool are 42.8%, 33.3%, 23.4% of /8 in the
      end of
      2016, 2017, and 2018, respectively. The remaining number of APNIC 103/8
      IPv4
      address pool for APNIC account holder is less and less. It is predicted
      that
      the 103/8 pool will be exhausted in 2020.

      Reducing the maximum IPv4 delegation size from APNIC 103/8 IPv4 address
      pool can
      prolong the exhaustion time of the 103/8. Newcomers of APNIC account
      holders will
      have the benefit in this period of time. New companies can obtain some
      IPv4 address
      space in the APNIC service region without the need to trade for address
      space and
      can make the preparation for the subsequent IPv6 migration.

      It is recommended that the number of assigned IPv4 addresses in Final /8
      be reduced
      from a maximum of /22 to /23. It will be estimated to extend the
      exhaustion time
      for at least three years or more.

      3. Situation in other regions

      There is no similar policy in place in other RIR regions.

      4. Proposed policy solution

      It is proposed to modify the 6.1 Minimum and maximum IPv4 delegations of
      the APNIC
      Internet Number Resource Policies[1].

      This proposal is to change the maximum size of IPv4 address delegations
      from the
      APNIC 103/8 IPv4 address pool[1] to a /23. /23 is important because new
      ISPs can
      use /24 for internal infrastructure and /24 customer assignments and NAT
      for IPv6
      transition.

      Current Policy text

      Each APNIC account holder is only eligible to receive IPv4 address
      delegations
      totalling a maximum /22 from the APNIC 103/8 IPv4 address pool.

      New Policy text

      Each APNIC account holder without APNIC 103/8 IPv4 address delegations
      from the
      APNIC 103/8 IPv4 address pool is only eligible to receive a maximum /23
      from the
      APNIC 103/8 IPv4 address pool.

      5. Advantages / Disadvantages

      Advantages:
      - This proposal allows a greater range of networks to access the
      resources in
      the final /8.

      • This proposal extends the maximum possible total number of networks that can benefit from the final /8 pool from around 16,000 to around 18,000 networks, providing small amounts of IPv4 to be available for networks, developing economy, etc., making the transition to IPv6 for many years to come.

      Disadvantages:
      - No disadvantages are foreseen.

      6. Impact on resource holders

      It reduces the maximum size of the delegated address block available to
      APNIC
      members during the final /8 phase. This will affect NIR members in the
      same way
      as APNIC members.
