[arin-ppml] LAST CALL - Draft Policy ARIN-2012-6: Revising Section 4.4 C/I Reserved Pool Size
The ARIN Advisory Council (AC) met on 20 December 2012 and decided to
send the following draft policy to last call:
Draft Policy ARIN-2012-6: Revising Section 4.4 C/I Reserved Pool Size
The AC revised the text after the ARIN XXX Public Policy Meeting and
asked for an updated staff assessment of the revised text. The
assessment is available at:
Feedback is encouraged during the last call period. All comments should
be provided to the Public Policy Mailing List. Last call for 2012-6 will
expire on 15 January 2013. After last call the AC will conduct their
last call review.

Draft Policy ARIN-2012-6
Revising Section 4.4 C/I Reserved Pool Size
Date: 27 December 2012
4.4. Micro-allocation ARIN will make IPv4 micro-allocations to critical
infrastructure providers of the Internet, including public exchange
points, core DNS service providers (e.g. ICANN-sanctioned root and ccTLD
operators) as well as the RIRs and IANA. These allocations will be no
smaller than a /24. Multiple allocations may be granted in certain
Exchange point allocations MUST be allocated from specific blocks
reserved only for this purpose. All other micro-allocations WILL be
allocated out of other blocks reserved for micro-allocation purposes.
ARIN will make a list of these blocks publicly available.
Exchange point operators must provide justification for the allocation,
including: connection policy, location, other participants (minimum of
two total), ASN, and contact information. ISPs and other organizations
receiving these micro-allocations will be charged under the ISP fee
schedule, while end-users will be charged under the fee schedule for
end-users. This policy does not preclude exchange point operators from
requesting address space under other policies.
ARIN will place an equivalent of a /16 of IPv4 address space in a
reserve for Critical Infrastructure, as defined in section 4.4. If at
the end of the policy term there is unused address space remaining in
this pool, ARIN staff is authorized to utilize this space in a manner
consistent with community expectations.
ICANN-sanctioned gTLD operators may justify up to the equivalent of an
IPv4 /23 block for each authorized new gTLD, allocated from the free
pool or received via transfer, but not from the above reservation. This
limit of a /23 equivalent per gTLD does not apply to gTLD allocations
made under previous policy.
Additional ICANN-sanctioned DNS infrastructure is being added to the
Internet and in quantities greater than anticipated when the micro
allocation proposal was written and adopted.
The original CI pool was created to serve new IXP and new CI
requirements. The pending need is estimated to be over 1000 new gTLD
range, which may exhaust the current /16 reservation before the ARIN
free pool is exhausted. Once the current /16 reservation is exhausted,
CI providers would no longer be eligible to receive address space,
either via the general free pool or via transfer.
The original proposal dealt with this by expanding the reservation to a
/15 and allowing CI to draw from the free pool instead of the
reservation until it gets down to a /8. The consensus coming out of the
Dallas meeting seems to be that this is an inadequate solution. As the
new expanded gTLD demand will obliterate any reasonable reservation,
leaving no resources for the other IXP and CI demands that the original
reservation was intended to serve. It is therefore, not possible to
services them both out of a common reservation.
In order to ensure continued access to IPv4 number resources by new IXP
and DNS operators alike, the AC is modifying the proposal going into
last call to allow gTLD operators to continue to qualify for micro
allocations from the general free pool or via transfer only, and leaving
one /16 reserved for IXP, root, and ccTLD DNS operators.
As a result of the close examination of the CI policy brought about by
this proposal, the AC has identified a number of issues in the original
policy text that should be addressed. However, the AC is intentionally
minimizing the overall changes to this proposal as much as possible for
last call in keeping with the spirit of the PDP. The AC intends to make
future proposals to deal with these other concerns. The current proposal
addresses issues of some urgency and we did not want to delay it to
another policy cycle as a result.
