Recommended Draft Policy ARIN-2015-3
Remove 30 day utilization requirement in end-user IPv4 policy
On 18 February 2016 the ARIN Advisory Council (AC) recommended
ARIN-2015-3 for adoption, making it a Recommended Draft Policy.
ARIN-2015-3 is below and can be found at:
https://www.arin.net/policy/proposals/2015_3.html
You are encouraged to discuss Draft Policy 2015-3 on the PPML prior to
its presentation at the next ARIN 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.

Recommended Draft Policy ARIN-2015-3
Remove 30 day utilization requirement in end-user IPv4 policy
AC's assessment of conformance with the Principles of Internet Number
Resource Policy:
ARIN 2015-3 contributes to fair and impartial number resource
administration by removing from the NRPM text that is operationally
unrealistic for the reasons discussed in the problem statement. This
proposal is technically sound, in that the removal of the text will more
closely align with the way staff applies the existing policy in relation
to 8.3 transfers. The proposal was supported by community members at the
ARIN PPM in Montreal and on PPML with some dissent.
Problem Statement:
End-user policy is intended to provide end-users with a one year supply
of IP addresses. Qualification for a one-year supply requires the
network operator to utilize at least 25% of the requested addresses
within 30 days. This text is unrealistic and should be removed.
First, it often takes longer than 30 days to stage equipment and start
actually using the addresses.
Second, growth is often not that regimented; the forecast is to use X
addresses over the course of a year, not to use 25% of X within 30 days.
Third, this policy text applies to additional address space requests. It
is incompatible with the requirements of other additional address space
request justification which indicates that 80% utilization of existing
space is sufficient to justify new space. If a block is at 80%, then
often (almost always?) the remaining 80% will be used over the next 30
days and longer. Therefore the operator cannot honestly state they will
use 25% of the ADDITIONAL space within 30 days of receiving it; they're
still trying to use their older block efficiently.
Fourth, in the face of ARIN exhaustion, some ISPs are starting to not
give out /24 (or larger) blocks. So the justification for the 25% rule
that previously existed (and in fact, applied for many years) is no
longer germane.
Policy statement:
Remove the 25% utilization criteria bullet point from NRPM 4.3.3.
Resulting text:
4.3.3. Utilization rate
Utilization rate of address space is a key factor in justifying a new
assignment of IP address space. Requesters must show exactly how
previous address assignments have been utilized and must provide
appropriate details to verify their one-year growth projection.
The basic criterion that must be met is a 50% utilization rate within
one year.
A greater utilization rate may be required based on individual network
requirements. Please refer to RFC 2050 for more information on
utilization guidelines.

ARIN STAFF ASSESSMENT
Draft Policy ARIN-2015-3
Remove 30 day utilization requirement in end-user IPv4 policy
Date of Assessment: 16 February 2016
___
1. Summary (Staff Understanding)
This proposal would remove the 25% utilization (within 30 days of
issuance) criteria bullet point from NRPM 4.3.3.
___
2. Comments
A. ARIN Staff Comments
This policy would more closely align with the way staff applies the
existing policy in relation to 8.3 transfers. Because there is no longer
an IPv4 free pool and many IPv4 requests are likely to be satisfied by
8.3 transfers, the adoption of this policy should have no major impact
on operations and could be implemented as written.
Note that both NRPM 4.3.3 and NRPM 4.2.3.6 contain references to
obsolete RFC 2050. Additionally, 4.2.3.6 references the 25% immediate
use (within 30 days of issuance) requirement.
Staff suggests removing the first two sentences of 4.2.3.6 to remove the
references to RFC 2050 and the 25% requirement. Additionally, staff
suggests removing the reference to the obsolete RFC 2050 in section 4.3.3.
B. ARIN General Counsel – Legal Assessment
No material legal risk in this policy.
___
3. Resource Impact
This policy would have minimal resource impact from an implementation
aspect. It is estimated that implementation would occur immediately
after ratification by the ARIN Board of Trustees. The following would be
needed in order to implement:
* Updated guidelines and internal procedures
* Staff training
