Draft Policy 2011-4: Reserved Pool for Critical Infrastructure

[ARIN]

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

On 28 January 2011 the ARIN Advisory Council (AC) selected "Reserved
Pool for Critical Infrastructure" as a  draft policy for adoption
discussion on the PPML and at the Public Policy Meeting in San Juan,
Puerto Rico in April.

The draft was developed by the AC from policy proposal "ARIN-prop-123.
Reserved Pool for Critical Infrastructure". Per the Policy Development
Process the AC submitted text to ARIN for a staff and legal assessment
prior to its selection as a draft policy. Below the draft policy is the
ARIN staff and legal assessment, followed by the text that was submitted
by the AC.

Draft Policy ARIN-2011-4 is below and can be found at:
https://www.arin.net/policy/proposals/2011_4.html

You are encouraged to discuss Draft Policy 2011-4 on the PPML prior to
the April Public Policy Meeting. Both the discussion on the list and
at the meeting will be used by the ARIN Advisory Council to determine
the community consensus for adopting this as policy.

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.

Rationale:

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

STAFF ASSESSMENT

Proposal: “Reserved Pool for Critical Infrastructure” (pp 123)
Policy Version (Date):  23 November 2010
Date of Assessment:  27 January 2011

1. Proposal Summary (Staff Understanding)

This policy would set aside a /16 equivalent when the IANA issues its
last /8 to ARIN. These addresses would be reserved for issuing under the
IPv4 micro-allocations for critical infrastructure policy (NRPM 4.4). If
any of the reserved addresses are unused 36 months after implementation,
ARIN may begin using the addresses for other purposes.

2. Comments

  A. ARIN Staff Comments

   • The proposal says, “reserve for critical infrastructure” but
doesn’t elaborate on what critical infrastructure actually is.   NRPM
4.4. ("Micro-allocation") defines a specific list of uses that qualifies
as critical infrastructure. For coherency, perhaps this policy should
specifically state that “critical infrastructure” as defined in NRPM
4.4. That way, there can be no misinterpretation of its meaning.

  B. ARIN General Counsel

No comments

3. Resource Impact

This policy would have minimal resource impact from an implementation
aspect.  It is estimated that implementation would occur within 3 months
after ratification by the ARIN Board of Trustees.

The following would be needed in order to implement:
  • Updated documentation on the ARIN website
