You are encouraged to discuss all Draft Policies on PPML. The AC will
evaluate the discussion in order to assess the conformance of this Draft
Policy with ARIN's Principles of Internet number resource policy as
stated in the Policy Development Process (PDP). Specifically, these
principles are:
* Enabling Fair and Impartial Number Resource Administration
* Technically Sound
* Supported by the Community

Draft Policy ARIN-2020-3: IPv6 Nano-allocations
Problem Statement:
ARIN’s ISP registration services fee structure has graduated fee
categories based upon the total amount of number resources held within
the ARIN registry.
In the case of the very smallest ISPs, if a 3X-Small ISP (with a /24 or
smaller of IPv4) gets the present minimal-sized IPv6 allocation (a /36),
its annual fees will double from $250 to $500/year.
According to a Policy Experience Report presented by Registration
Services to the AC at its annual workshop in January 2020, this
represents a disincentive to
IPv6 adoption with a substantial fraction of so-situated ISPs saying "no
thanks" and abandoning their request for IPv6 number resources when
informed of the impact on their annual fees.
This can be addressed by rewriting subsection 6.5.2.1(b). Initial
Allocation Size to allow allocation of a /40 to only the smallest ISPs
upon request, and adding a new clause 6.5.2.1(g) to cause an automatic
upgrade to at least a /36 in the case where the ISP is no longer 3X-Small.
Reserving /40s only for organizations initially expanding into IPv6 from
an initial sliver of IPv4 space will help to narrowly address the
problem observed by Registration Services while avoiding unintended
consequences by accidentally giving a discount for undersized allocations.
Policy statement:
Replace the current 6.5.2.1(b) with the following:
b. In no case shall an LIR receive smaller than a /32 unless they
specifically request a /36 or /40.
In order to be eligible for a /40, an ISP must meet the following
requirements:
* Hold IPv4 direct allocations totaling a /24 or less (to include zero)
* Hold IPv4 reassignments/reallocations totaling a /22 or less (to
include zero)
In no case shall an ISP receive more than a /16 initial allocation.
Add 6.5.2.1(g) as follows:
g. An LIR that requests a smaller /36 or /40 allocation is entitled to
expand the allocation to any nibble aligned size up to /32 at any time
without renumbering or additional justification. /40 allocations shall
be automatically upgraded to /36 if at any time said LIR's IPv4 direct
allocations exceed a /24. Expansions up to and including a /32 are not
considered subsequent allocations, however any expansions beyond /32 are
considered subsequent allocations and must conform to section 6.5.3.
Downgrades of any IPv6 allocation to less than a /36 are not permitted
regardless of the ISP's current or former IPv4 number resource holdings.
Comments:
The intent of this policy proposal is to make IPv6 adoption at the very
bottom end expense-neutral for the ISP and revenue-neutral for ARIN.
The author looks forward to a future era wherein IPv6 is the dominant
technology and IPv4 is well in decline and considered optional leading
the Community to conclude that sunsetting this policy is prudent in the
interests of avoiding an incentive to request undersized IPv6 allocations.
Timetable for implementation: Immediate
