      APNIC welcomes comments, questions, and suggestions on the following policy proposal:


      Final call for comments: [prop-021-v001]
      "Expansion of the initial allocation space for existing IPv6 address
      space holders"

      This is the final call for comments on policy proposal [prop-021-v001]
      "Expansion of the initial allocation space for existing IPv6 address
      space holders". This is a proposal to allow existing IPv6 address
      holders to expand their initial allocation, using their existing IPv4 infrastructure to justify an allocation larger than a /32. The use of
      IPv4 infrastructure to justify a larger initial allocation was passed
      at APNIC 17 [prop-016-v002]. This current proposal allows networks
      that received an initial allocation before prop-0160-v001 to be given
      the same opportunity to recieve an initial allcoation greater than /32.

      This proposal was presented at APNIC 18 and the following consensus was

      "to implement the proposal to expand IPv6 address space holdings
      for existing users without satisfying the subsequent allocation

      This proposal is now submitted to the sig-policy mailing list for an
      eight week discussion period. At the end of that period, if consensus
      appears to have been achieved, the Chair of the Policy SIG will
      ask the Executive Council to endorse the proposal for implementation.

      Proposal details


      I propose making it possible for existing IPv6 address holders with
      the initial allocation address space to expand their address space
      without clearing the subsequent allocation requirement.

      This proposal has reached a consensus at JPNIC Open Policy Meeting.

      Summary of the current problem:

      In the past, many of the organizations had requested for the minimum
      allocation size(/32) as an initial allocation due to the following

      + Based on the idea of the "slow start" in IPv4 policy, many
      organizations believed it would be difficult to justify all of their
      address requirements at an initial allocation.

      + It was difficult to estimate their needs as IPv6 network was not
      commercially developed. Many organizations requested for address
      space for a test service in order to kick off the commercial
      service, not for the commercial service itself.

      specified the initial allocation size as /35. LIRs which received
      allocations under this policy were only allowed an upgrade of
      their allocations to a /32.

      In recent days, most of the ISPs learned that /32 space is too small
      for the real scale service deployment if they cover their existing
      IPv4 users.

      Organizations currently requesting for initial allocations can simply
      request for a larger space as the RIRs actively emphasize to their
      communities that they are able to request for allocations greater than
      /32, which is already a common practice.

      However, ISPs with the default address space need to design the IPv6
      service network within the small space untill they clear the
      subsequent allocation requirement (HD-Ratio) for more address
      space. This makes the real IPv6 service deployment difficult,
      especially for large ISPs.

      Situation in other RIRs:


      Details of your proposal:

      Existing IPv6 initial allocation address holders should be able to
      expand their address space without satisfying subsequent allocation
      criteria if they are able to demonstrate their concrete plan. The same
      criteria should apply as organizations requesting for an initial
      allocation larger than /32.

      This proposal does not intend to change the current policy but to
      apply the current allocation practice to existing IPv6 address

      If it is possible to expand the address space under the current
      policy, it is desirable to be documented clearly (e.g. in the
      guidelines document).

      Advantages and disadvantages of adopting the proposed policy:


      Existing IPv6 address holders will be possible to start their services
      under up-to-date situation.



      Effect on APNIC members:

      The expanded address space would be considered in the assessment of
      the APNIC membership tier of the organization, on the renewal of their

      Effect on NIRs:

      NIRs providing IPv6 address allocation service should apply the same
