Re: NIR-SIG at APNIC18 - Call for presentations and new co-chair(s)
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
