The following is the proposed update for ARIN-2015-3: Remove 30-Day 
Utilization Requirement in End-User IPv4 Policy based on strong support 
in Montreal.

Beyond deleting the 25% bullet as the policy says, their are editorial 
changes as follows to the remaining text;

- It looks weird to have single item bullet list, so merge the two 
remaining sentence fragments into a single sentence.
- Change "are" to "is", since there is only one remaining criteria
- Use of "criteria" as a singular is common usage, even though 
technically it's plural.
- Resulting in "The basic criteria that must be met is a 50% utilization 
rate within one year."

The remaining and resulting text for 4.3.3 is now included in the policy 
text, for editorial clarity.  The original staff and legal suggested 
removing the RFC2050 reference and also pointed out that also has a 25% immediate use clause and a RFC2050 reference.

Feedback in Montreal was that deleting the 25% immediate use was a nice 
bite-sized change, and we shouldn't try to do more than that with this 
change, so those changes are not included at this time.

Any additional feedback or comments are appreciated.



Draft Policy ARIN-2015-3: Remove 30 day utilization requirement in 
end-user IPv4 policy

Date: 27 January 2015

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 criteria that must be met is a 50% utilization rate within one 

A greater utilization rate may be required based on individual network
requirements. Please refer to RFC 2050 for more information on
utilization guidelines.
