      "Situation in other RIRs".
      
      We invite you to review and comment on the proposal on the mailing list
      before the meeting.

      Version:   2
      
      Date:      28 July 2008
      
      
      1.  Introduction
      ----------------
      
      This is a proposal to include all historical address allocations when
      assessing a network's eligibility for more IPv4 addresses.
      
      
      2.  Summary of current problem
      ------------------------------
      
      The unallocated pool of IPv4 addresses is predicted to run out within
      the next few years.  As the unallocated pool dwindles, it is important
      to ensure that the remaining IPv4 addresses are allocated responsibly
      and fairly.
      
      Currently, when LIRs apply for new IPv4 allocations from APNIC, they
      only have to include the past allocations they have received from
      APNIC as part of the documentation and justification process.  They do
      not have to declare any historical addresses [1] they may have
      received prior to receiving address space from APNIC.
      
      As a result of this, there is a large amount of historical IPv4
      address space where little or nothing is known about its use.
      
      At the moment LIRs can receive more scarce IPv4 address space from APNIC
      while at the same time hoarding unused historical address space.  This
      uses up the remaining IPv4 pool more rapidly than is really necessary.
      
      
      3.  Situation in other RIRs
      ---------------------------
      
      The situation in other RIRs is as follows:
      
      AfriNIC and the RIPE NCC only ask for utilisation of previous
      allocations and assignments made by AfriNIC and the RIPE NCC
      respectively.  They do not require legacy holdings to be declared.
      
      ARIN and LACNIC always ask for utilisation for all previous
      allocations and assignments, including all legacy holdings.
      
      This proposal has not been submitted to any other region.
      
      
      4.  Details of the proposal
      ---------------------------
      
      This is a proposal to modify the criteria for receiving IPv4 address
      space so that both historical addresses and previous allocations are
      included.
      
           - This proposal applies to all historical IPv4 resources
             registered in the APNIC Whois Database.
      
           - Historical IPv4 resources that are not managed under the
             existing historical maintenance or transfer policies will remain
             free of fees.
      
      
      5.  Advantages and disadvantages of the proposal
      ------------------------------------------------
      
      5.1 Advantages
      
           - Ensures that organisations are using scarce IPv4 address space
             resources to the fullest extent possible.
      
           - The utilisation of historical IPv4 addresses will be brought
             into line with current best practices for address management.
      
           - The remaining IPv4 free pool will be delegated to LIRs that have
             a genuine need for IP addresses.
      
      
      5.2 Disadvantages
      
           - Organisations can no longer hoard unused address space while at
             the same time receive more scarce address space from APNIC's
             pool.
      
           - LIRs with historical IPv4 addresses may find it time consuming
             to change network architecture that uses historical IPv4
             addresses in an inefficient manner.
      
             However, the difficulties felt by these networks is outweighed
             by the greater benefits of ensuring that the remaining IPv4
             address space is delegated to networks with a genuine need for
             IPv4 allocations.
      
      
      6.  Effect on APNIC members
      ---------------------------
      
      APNIC members who have applied best practices for address space
      management for all their address ranges will not be affected.
      
      APNIC members who have not applied best practices for all their
      address ranges may need to modify their management of historical
      addresses before they can qualify for IPv4 addresses from APNIC.
      
      There will be no impact on fees paid by members.
      
      
      7.  Effect on NIRs
      ------------------
      
      The proposal has no direct impact on NIRS, but impacts members of NIRs
      in the same way it impacts APNIC members.
