      prop-102: Sparse allocation guidelines for IPv6 resource allocations

      Dear colleagues

      The eight-week final comment period for the proposal 'Sparse allocation
      guidelines for IPv6 resource allocations' has ended. During the comment
      period there were no objections raised to the proposal. The Chairs
      therefore deem that consensus has been maintained on the proposal.

      We formally request that the APNIC Executive Council endorse this

      For a detailed history of this proposal see:

      prop-102-v003: Sparse allocation guidelines for IPv6 resource


      Author:  Dean Pemberton
                   <dean at deanpemberton dot com>

      1.  Introduction

      This proposal also requires that the details of any sparse allocation
      algorithm used for the allocation by APNIC of IPv6 resourcesmust be
      published on the website, and any revisions should be handled inline
      with the procedures contained within APNIC-112.

      2.  Summary of the current problem

      Large networks and economies are requesting  blocks of IPv6 space larger
      than the current allocation models allow. At present the allocation
      strategies look at a timeline on the order of 1-2 years.  Organisations
      are now having to look to a 5-10 year time-frame when deploying large
      IPv6 networks.

      They are understandably concerned about their ability to secure access
      to 5-10 years of aggregatable address space if they are only allocated
      on 1-2 year needs basis. We have seen requests in proposals such as
      prop-98, prop-99 and prop-100, which seek to find ways to allow for
      larger allocations or reserve an amount of space for future
      organisational use. All of these proposals seek to make large changes to
      the way that IPv6 addresses are allocated by APNIC in order to address
      these legitimate concerns.

      It would seem however that there is an alternative solution which would
      only require a small change to current operating procedure.

      At present the APNIC operating procedure is for hostmasters to use a
      method of sparse-allocation when allocating IPv6 addresses out of the
      APNIC free pool.

      The sparse-allocation allows for allocations to be given from a larger pool
      in such a way that members can request neighbouring allocations at a later
      date and aggregate these together in to a larger routable allocation.

      While this has been APNIC operating procedure for some time, the
      specific details of the algorithm have not been publically published.
      As such the exact algorithm used as well as the parameters around this
      sparse-allocation algorithm are not open to member input or comment
      through a consultation process.

      3.  Situation in other RIRs

      Unknown at this point.

      4.  Details

      This proposal seeks to make the following additions/changes to APNIC

          1.  APNIC must publish the details of any sparse allocation
              framework on the APNIC website as a numbered document.  Changes
              to this document should be handled as per APNIC-112 "APNIC
              document editorial policy".

      5.  Pros/Cons


          -  APNIC Members will have visibility of the details of any sparse
             allocation algorithm used by APNIC to allocate IPv6 resources


          -  The hostmasters would be required to document and publish the
             sparse allocation mechanism.

             This may have an increased workload requirement.  It is not
             anticipated that this increase would be significant as changes to
             the algorithm are not expected to occur frequently.

      6.  Effect on APNIC Members

      APNIC members would be able to see the published details of the sparse
      allocation policy used by APNIC to allocate IPv6 resources from its
      address pool.

      7.  Effect on NIRs

      The policy would apply when NIRs request address space from APNIC
      The proposal allows NIRs to choose when to adopt this policy for their
