Draft Policy ARIN-2011-4
Reserved Pool for Critical Infrastructure

Version/Date: 23 November 2010

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, 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.


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
