Policy Proposal 123: Reserved Pool for Critical Infrastructure

Proposal Originator: Martin Hannigan

Proposal Version: 3.0

Date: 23 Nov 2010

Proposal type: Modify

Policy term: 36 Months following implementation

Policy statement:

Upon receipt of the last /8 that the IANA will allocate to ARIN per the
Global Policy for the Allocation of the Remaining IPv4 Address Space,
ARIN will place an equivalent of a /16 of IPv4 address space in a
reserve for Critical Infrastructure. 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


Section 4.10 of the NRPM is insufficient with respect to insuring the
continued operation of critical infrastructure. This proposal, if
adopted, will protect those resources with a reasonable amount of
reserved v4 address space and prevent an overrun of CI needs by NRPM
Section 4.10 or any successor. The intent is to separate CI needs and
make a distinct pool available to insure the continuity of CI
allocations per NRPM Section 4.4 for at least 36 months.

This proposal should be considered an emergency proposal. IANA
exhaustion is likely to occur prior to the next ARIN meeting.

Timetable for implementation: Immediate
