Recommended Draft Policy ARIN-2014-21
Modification to CI Pool Size per Section 4.4

Date: 25 November 2014

AC's assessment of conformance with the Principles of Internet Number 
Resource Policy:

This proposal enables fair and impartial number resource administration 
by ensuring IPv4 resources are available for critical infrastructure and 
Internet Exchanges in particular after IPv4 resources are no longer 
readily available from the ARIN free pool. This benefits more than just 
the individual organizations receiving these resources; it benefits the 
entire Internet Community by contributing to the stability and 
scalability of the Internet as a whole. This proposal is technically 
sound and is supported by the community.

Problem Statement:

At the time that this section of policy was written, IXP growth in North 
America was stagnant. Efforts of late have increased significantly 
within the IXP standards and other communities to improve critical 
infrastructure in North America. This effort is paying dividends and we 
project that a /16 will not be enough to continue to improve global 
interconnect conditions and support needed IXP CI infrastructure.

Policy statement:

Change to text in section 4.4 Micro Allocations:

Current text:

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.

Proposed text to replace current text entirely:

ARIN will place an equivalent of a /15 of IPv4 address space in a 
reserve for Critical Infrastructure, as defined in section 4.4.

Timetable for implementation: Immediate

ARIN STAFF ASSESSMENT

Draft Policy ARIN-2014-21: Modification to CI Pool Size per Section 4.4
Date of Assessment: 14 January 2015

1. Summary (Staff Understanding)

This policy changes one section of existing NRPM policy 4.4 to extend 
the current reservation size for critical infrastructure and exchange 
points from a /16 equivalent to a /15 equivalent.


2. Comments

A. ARIN Staff Comments

• For informational purposes:
• A total of 35 /24s have been issued from the reserved /16 equivalent 
for CI and IXPs since the policy was amended and implemented on 20 March 
2013, leaving 221 /24s available in this reserved block.

• There are currently 381 free /24s remaining in the two /8 ranges 
used for CI and IXP micro-allocations.

• This policy could be implemented as written.


B. ARIN General Counsel - Legal Assessment

This proposal does not create any material legal issue.

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 guidelines and internal procedures
· Staff training
