      1.  Introduction
      ----------------
      The exhaustion of IPv4 address space is projected to take place within
      the next few years. This proposal seeks to focus on measures that should
      be taken globally in the address management area in order to prepare for
      the situation in all RIR regions.
      
      
      2.  Summary of current problem
      ------------------------------
      To continue applying a global coordinated policy for distribution of the
      last piece(s) of each RIR's unallocated address block does not match the
      reality of the situation in each RIR region.
      
      Issues each RIR region will face during the exhaustion period vary by
      region as the level of development of IPv4 and IPv6 are widely
      different. As a result, applying a global co-ordinated policy may not
      adequately address issues in a certain region while it could be work for
      the others.
      
      For example, in a region where late comers desperately need even small
      blocks of IPv4 addresses to access to the IPv4 Internet, a policy that
      defines the target of allocations/assignments of IPv4 address space to
      be late comers would be appropriate in such region. This would allow
      availablilty of IPv4 address space for such requirements for more years.
      
      Another example comes from difference in IPv6 deployment rate. For a
      region where IPv6 deployment rate is low, measures may be necessary to
      prolong IPv4 address life for the existing business as well as for new
      businesses until networks are IPv6 ready. Some regions may have strong
      needs to secure IPv4 address space for translators.
      
      A globally coordinated policy which addresses all the issues listed
      above to meet the needs for all RIR regions may result in not solving
      issues in any of the regions.
      
      
      3.   Situation in other RIRs
      ----------------------------
      This proposal will be submitted to all RIRs. It is a collaboration
      between the authors of the previous proposals:
      
          prop-046: IPv4 countdown policy proposal
          prop-051: Global policy for the allocation of the remaining IPv4
                    address space
      
      These two proposals were deemed by a number of people in the RIR
      communities to be similar; and at the ARIN XXI meeting, the authors of
      both proposals were asked to work together to produce a single
      proposal.
      
      
      4.   Details of the proposal
      ----------------------------
      This policy describes the process for the allocation of the remaining
      IPv4 space from IANA to the RIRs. When a minimum amount of available
      space is reached, one /8 will be allocated from IANA to each RIR,
      replacing the current IPv4 allocation policy.
      
      In order to fulfill the requirements of this policy, at the time it is
      adopted, one /8 will be reserved by IANA for each RIR. The reserved
      allocation units will no longer be part of the available space at the
      IANA pool. IANA will also reserve one /8 to any new RIR at the time it
      is recognized.
      
      The process for the allocation of the remaining IPv4 space is divided in
      two consecutive phases:
      
           4.1. Existing Policy Phase:
      
              During this phase IANA will continue allocating IPv4 addresses
      	to  he RIRs using the existing allocation policy. This phase
      	will continue until a request for IPv4 address space from any
      	RIR to IANA either cannot be fulfilled with the remaining IPv4
      
      space available at the IANA pool or can be fulfilled but leaving the IANA remaining IPv4 pool empty.
      
              This will be the last IPv4 address space request that IANA will
              accept from any RIR. At this point the next phase of the process
              will be initiated.
      
           4.2. Exhaustion Phase:
      
              IANA will automatically allocate the reserved IPv4 allocation
              units to each RIR (one /8 to each one) and respond to the last
              request with the remaining available allocation units at the
              IANA pool (M units).
      
              4.2.1. Size of the final IPv4 allocations:
      
                     During this phase IANA will automatically allocate one
                     /8 to each RIR from the reserved space defined in this
                     policy. IANA will also allocate M allocation units to
                     the RIR that submitted the last request for IPv4
                     addresses.
      
              4.2.2. Allocation of the remaining IPv4 Address space:
      
                     After the completion of the evaluation of the final
                     request for IPv4 addresses, IANA MUST:
      
                     A) Immediately notify the NRO about the activation of the
                        second phase of this policy.
      
                     B) Proceed to allocate M allocation units to the RIR that
                        submitted the last request for IPv4 address space.
      
                     C) Proceed to allocate one /8 to each RIR from the
                        reserved space.
      
      
      
      5.   Advantages and disadvantages of the proposal
      -------------------------------------------------
      Advantages:
      
      - It allows each RIR community to define a policy on how to distribute
        the last piece(s) of allocations which best matches their situation.
      
      
      Disadvantages:
      
      - Concerns could be raised about allocating a fixed size to all RIRs,
        that it artificially fastens the consumption rate of some RIR
        regions.  However, its impact is kept to minimum by keeping the
        allocation size to a single /8 which makes merely 3-4 months
        difference.
      
      - Concerns could be raised that explicitly allowing regional policies
        will encourage RIR shopping. However, this should not happen if the
        requirements within each region is adequately reflected in each RIR's
        policy through PDP. RIR may also chose to add criteria to prevent
        LIRs from other regions submitting such requests.
      
      
      6.   Effect on APNIC members
      ----------------------------
      APNIC members will be able to define  a policy on how to distribute the
      last piece(s) of allocations which best matches the situation in AP
      region.
      
      
      7.   Effect on NIRs
      -------------------
      The effect on APNIC members applies to members of NIRs. NIRs are
      therefore expected to inform their communities of the situation.
