Recommended Draft Policy ARIN-2014-13
Reduce All Minimum Allocation/Assignment Units to /24

Date: 20 May 2014

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

Draft Policy ARIN-2014-13: Reduce All Minimum Allocation/Assignment Units to /24 - This proposal will lower all allocation(s) and assignment(s) of IPv4 address in section 4.2 and 4.3 to a /24 minimum. The policy would also remove section 4.9 as the allocation and assignment sizes were now larger than 4.2 and 4.3. As noted in the staff report it will also remove the maximum initial allocation that was used with the examples in 4.2.2.2. The changes to the NRPM are fair in that they would treat all resource applicants equally. They are technically sound and have received support from the community.

Problem Statement:

As we approach runout, more and more end users and smaller ISPs will be unable to obtain space from their upstreams and will be seeking space from ARIN. In order to meet these needs to the extent possible and to make policy more fair to a broader range of the ARIN constituency, we should reduce the minimum assignment and allocation units for IPv4 to /24 across the board.

Policy statement:

Remove all references to minimum allocations /20 and /22 replacing them with the term allocation or with /24 when referencing minimum size blocks.

Change the title of 4.2.2.1 to "ISP Requirements" with revised text stating:

All ISP organizations must satisfy the following requirements...thus eliminating the entire Multi-homed section and subsections along with other superfluous example text.

Delete the special case allocations/assignments for the Caribbean as the new /24 minimums are an improvement.

Full text version of changes for easy reference:

4.2.1.5. Minimum allocation
In general, ARIN allocates /24 and larger IP address prefixes to ISPs. If allocations smaller than /24 are needed, ISPs should request address space from their upstream provider.

4.2.2.1 ISP Requirements
All ISP organizations must satisfy the following requirements:

4.2.2.1.1 Use of /24
The efficient utilization of an entire previously allocated /24 from their upstream ISP. This allocation may have been provided by an ISP’s upstream provider(s), and does not have to be contiguous address space.

4.2.2.1.3. Three months
Provide detailed information showing specifically how the requested allocation will be utilized within three months.

4.2.2.1.4. Renumber and return
ISPs receiving a new allocation may wish to renumber out of their previously allocated space. In this case, an ISP must use the new allocation to renumber out of that previously allocated block of address space and must return the space to its upstream provider.

4.2.2.2. [section number retired]

4.3.2 Minimum assignment

4.3.2.1. [section moved to 4.3.2]
The minimum block of IP address space assigned by ARIN to end-users is a /24. If assignments smaller than /24 are needed, end-users should contact their upstream provider.

4.3.2.2 [section number retired]

4.9 [section number retired]

ARIN STAFF ASSESSMENT
Assessment of: ARIN-prop-208 Reduce All Minimum Allocation/Assignment Units to /24
Date of Assessment: 11 May 2014

1. Summary (Staff Understanding)

This policy would reduce the minimum allocation/assignment size to /24 for all networks, whether end user or ISP and whether single or multi-homed. Additionally, it would eliminate the existing multi-homed policies.

2. Comments

A. ARIN Staff Comments

1. It is not clear in this proposal what criteria would be used to determine any allocation size other than a /24. Current policy provides clear criteria for how to qualify for a /22, /21, and a /20. Would the same criteria still apply for organizations that request more than an initial allocation of a/24?

2. Staff uses current criteria defined in 4.2.2.1.1 in conjunction with section 4.2.1.4 (slow start) to establish a de facto /20 maximum initial allocation size for ISPs new to ARIN. Staff would recommend that a maximum initial allocation size of a /20 be noted in section 4.2.1.5 to codify existing practice and provide clarity, and that it be renamed to “Minimum and Maximum Allocation”.

3. This proposal would benefit smaller ISPs who are unable to qualify currently under ARIN IPv4 policies, and particularly would be unable to qualify for 8.3 and 8.4 transfers in a post-depletion world.
*Note, this was a point raised in the policy experience report in Chicago.

4. ARIN will likely have many discontiguous /24s as we near depletion and fewer and fewer larger prefixes. This policy would actually allow more organizations to use these smallest prefixes, thus ensuring the efficient run-out of ARIN’s IPv4 address pool.

B. ARIN General Counsel - Legal Assessment

This proposal does not appear to pose any legal risk.

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

4.3.2.1. [section moved to 4.3.2]
The minimum block of IP address space assigned by ARIN to end-users is a /24. If assignments smaller than /24 are needed, end-users should contact their upstream provider.

4.3.2.2 [section number retired]
