      The following is the proposal I have submitted online yesterday.
      
      I am looking forward to have discussions with you at Fiji, but any
      feedbacks or comments in advance are also very welcome.
      
      
      Best Regards,

      Title: A proposal to abolish redundant charges in  IPv6 allocations
      
      Introduction: This paper proposes to revise a method of calculating IPv6 per
      address fee  so that multiple fees charged for the same address range will
      be abolished.
      
      Summary: "Per address fee" is the fee charged for allocations which NIRs or
      NIR members receive. Therefore, per address fee should only be charged for
      newly allocated ranges. 
      
      However, the current per address fee scheme defined in APNIC-081 "APNIC Fee
      Schedule: Membership Tiers, Fees, and Descriptions" ,leads to multiple
      charges for the same address range in IPv6 allocations. The following how it
      is defined in the document:
      
      APNIC-081 "APNIC Fee Schedule: Membership Tiers, Fees, and Descriptions" 
        3.4.3  IPv6 address space
      
      	For an allocation of IPv6 address space, the total per-
      	address fee is calculated for the prefix allocated according
      	to the number of addresses which should be utilised according
      	to an HD-Ratio of 0.80.
      
              (snip..)
      
      	In the case of an allocation which includes a previously
      	allocated block of addresses, the total fee calculation is
      	based on the size of the prefix allocated, regardless of the
      	previous allocation.
      
      Under this scheme, NIRs will be charged for the address space which had been
      previously charged when they receive subsequent allocations which are
      contiguous from previous allocations(see the chart below).
      
      +-----+  
      | /32 |
      +-----+
       (new allocation)
       (charge)
      
      
      +-----------+
      |    /31    |
      +-----------+
              (new allocation - /32)
       (charge)
      
      +--------------------------+
      |           /30            |
      +--------------------------+
                    (new allocation - /31)
       (charge)
      
      As a result, NIRs must either come up with a way to cover the redundant
      charge without charging their memebrs, or apply the same scheme to their
      members. JPNIC applies the same scheme, but we are unable to make a
      reasonable justification. 
      
      Furtheremore, it  leads to LIRs which conserve address space(requesting for
      small allocations as a start) have to
      pay more fee than LIRs which request for large allocations  at once:
      
      (case-1) /32 initially, then upgrade to /31, /30, until /29
      
       Initial allocation (/32)              : 7,132 * per address fee
       Second allocation (/32, /31 in total) : 12,417 * per address fee
       Third allocation (/31, /30 in total)  : 21,619 * per address fee
       Fourth allocation (/30, /29 in total) : 37,641 * per address fee
      -------------------------------------------------------------------
       Fee total                             : 78,809 * per address fee
      
      
      (case-2) /29 initial allocation
      
       Initial allocation (/29) : 37,641 * per address fee
      
      Situation: N/A
      
      Details: The proposal is to replace APNIC-081 as below;
      
      
        3.4.3  IPv6 address space
      
      	For an allocation of IPv6 address space, the total per-
      	address fee is calculated for the prefix allocated according
      	to the number of addresses which should be utilised according
      	to an HD-Ratio of 0.80.
      
              (snip..)
      
      	In the case of an allocation which includes a previously
      	allocated block of addresses, the total fee calculation is
      	based on the difference in the number of /48s  corresponding
              to HD-ratio 0.8, between the previous allocation and the new
              allocation.
      
              For example, the total per-address fee payable for an
      	allocation of /30 including previous /32 allocation to a "Very
              Large" member is calculated as:
      
                 (21,619 - 7,132) x $ 0.03 = $ 434.61
      
              Note: The number of /48s for /32 under HD ratio 0.8:  7,132
                    The number of /48s for /30 under HD ratio 0.8: 21,619
      
      Pros/Cons: Adopting the proposed method of fee calculation would lead to:
      
      Advantages
      1) Multiple fees will no longer be charged for the same address range.
      
      2) Same fee will be charged in total regardless of the size of past
      allocations.
      
      (case-1') /32 initially, then upgrade to /31, /30, until /29
      
       Initial allocation (/32)              : 7,132 * per address fee
       Second allocation (/32, /31 in total) : (12,417-7,132) * per address fee
       Third allocation (/31, /30 in total)  : (21,619-12,417) * per address fee
       Fourth allocation (/30, /29 in total) : (37,641-21,619) * per addless fee
      -------------------------------------------------------------------
       Fee total                             : 37,641 * per address fee
      
      
      (case-2') /29 initial allocation
      
       Initial allocation (/29) : 37,641 * per address fee 
                                   = case-1'
      Disadvantages:
      None.
      
      Effect on APNIC: No effect on APNIC members.
      
      Effect on NIRs: NIRs(and indirectly, NIR members) are no longer required to
      pay multiple per address fee for the same address range
