Policy Proposal 124: Clarification of Section

Proposal Originator: Martin Hannigan and Chris Grundemann

Proposal Version: 1.0

Date: 2 December 2010

Proposal type: Modify, complete replacement of

Policy term: Permanent

Policy statement: Subscriber Members After One Year

After an organization has been a subscriber member of ARIN for one year,
that organization may choose to request up to a 12 month supply of IP

On the date that ARIN receives its last /8 as a result of the IANA
executing section of the NRPM and in accordance with the Global
Policy for the Allocation of the Remaining IPv4 Address Space, the
length of supply that any organization may request from ARIN from that
moment forward will be reduced to three months. Any pending request
submitted prior to that moment will continue to be eligible for a twelve
month supply of addresses as long as need is established within thirty
days of that moment.


ARIN's pending operational practice is that if an organization has a
request in the ARIN hostmaster queue for IPv4 resources when the IANA
declares the exhaustion phase (, their request will be
automatically truncated from a twelve month supply to a three month
supply since policy in effect at the time of exhaustion will apply. 8.3
and are currently "in effect".

Example: If an entity is asking for 4 x /24 for a 12 month period and
IANA exhaustion occurs, a requester will receive, if justified, 1 x /24.
If an entity is asking for 120 x /24 at the time that exhaustion occurs,
they would only receive 30 x /24 if justified. If ARIN determines that
this same entity would only qualify for 90 of the 120 x /24 requested,
then that entity would only receive 22 x /24.

ARIN has the equivalent of almost a /8 in at least one reserve, has
recently received 2 /8's, received ~391 x /16's as a result of the
distribution of "various registries" from the IANA and is guaranteed to
receive at least one additional /8 (aggregate of about 92 million
individual IPv4 addresses) as a result of the execution of by
the IANA. Considering the size of the supply, it would seem prudent to
provide for all members needs in a fair and consistent manner as long as
possible in order to support the continued orderly transition of the
Internet to IPv6.

The ARIN AC should review and determine what action if any should be
taken at their next available opportunity, or sooner if they deem warranted.
