Policy Proposal 123: Reserved Pool for Critical Infrastructure

Proposal Originator: Martin Hannigan

Proposal Version: 2.0

Date: 20 Nov 2010

Proposal type: Modify

Policy term: 36 Months from 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 a contiguous /16 in 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 expectations.


During the recent attempted fix of Section 4.10 we had consensus that
4.10 was insufficient and potentially damaging and unbalanced with
respect to transition efforts. In order to enable the community to work
to fix this problem in a responsible manner, we need to insure that we
do not break the Internet or cause unnecessary hardship and cost. This
policy will protect those resources with a reasonable amount of reserved
v4 address space and prevent a possible overrun of CI needs by NRPM
Section 4.10 or any succesor. The intent is to separate CI needs and
make a distinct pool available to insure v4 continuity for CI 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
