Recommended Draft Policy ARIN-2014-19
New MDN Allocation Based on Past Utilization
On 18 December 2014 the ARIN Advisory Council (AC) recommended
ARIN-2014-19 for adoption, making it a Recommended Draft Policy.
ARIN-2014-19 is below and can be found at:
https://www.arin.net/policy/proposals/2014_19.html
You are encouraged to discuss Draft Policy 2014-19 on the PPML prior to
the upcoming ARIN Public Policy Consultation at NANOG 63 in San Antonio
in February 2015. 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-2014-19
New MDN Allocation Based on Past Utilization
Date: 16 December 2014
AC's assessment of conformance with the Principles of Internet Number
Resource Policy:
This draft policy enables fair and impartial number resource
administration by removing an impediment to additional allocations seen
by some organizations due to the recent policy changes under
ARIN-2013-08. This draft policy applies equally to all organizations and
allows for MDN organizations to use previous utilization of a site to
justify a new allocation for an MDN network site. The policy is clear
and implementable as written. This proposal is technically sound. There
are no technical issues which are raised by allowing a new criteria set
to justify a new MDN network allocation. This proposal is supported by
the community. Specifically, the draft policy is supported by
organizations which use the MDN policy for their network allocation.
Problem Statement:
The previous MDN policy was too limiting in that a new MDN could only
qualify under immediate need. This was extended by ARIN-2013-8 where the
minimum allocation will now be assigned unless immediate need for more
can be demonstrated.
Unfortunately, this policy did not go far enough. There may be some
cases where there is a one year utilization history that is applicable
to a new MDN. For example, imagine a network that is divided into four
regions, each an MDN. Three of the four MDNs have been growing at a /20
per year. The fourth MDN has been growing at a /19 per year, it is over
80% utilized, and the region is too large. The region will be divided in
half, which half of the current customers and their addresses to be
migrated into a new MDN (Region 5). It is also anticipated that half of
Region 4's growth will be shifted to Region 5. With Region 4 and Region
5 each above 80%, both should qualify for subsequent allocations at half
of what was Region 4's growth rate.
Policy statement:
replace section 4.5.4 created by 2013-8:
Upon verification that the organization has shown evidence of deployment
of the new discrete network site, the new network(s) shall be allocated
the minimum allocation size under section 4.2.1.5 unless the
organization can demonstrate additional need using the immediate need
criteria (4.2.1.6).
with:
Upon verification that the organization has shown
evidence of deployment of the new discrete network site, the new
network(s) shall be allocated one of the following:
- the minimum allocation size under section 4.2.1.5
- more than the minimum if the organization can demonstrate additional
need using the immediate need criteria (4.2.1.6)
- a 3-month supply of address space may be requested if the new MDN can
show a demonstrated one-year utilization history.
Timetable for implementation: Immediate
Comment:
The third bullet was changed from:
"- a three month supply if there is an applicable one year utilization
rate, specific to the use to be covered by the new MDN, on which to base
a three month supply on as per 4.2."
to:
"- a 3-month supply of address space may be requested if the new MDN can
show a demonstrated one-year utilization history."

ARIN STAFF ASSESSMENT
Date of Assessment: 22 October 2014
1. Summary (Staff Understanding)
This policy proposes to change existing NRPM 4.5, “Multiple Discrete
Networks� bullet 7 to add an additional qualifying criteria. Currently
new sites applying under MDN will qualify for the minimum allocation
size specified in 4.2.1.5 or under immediate need. This proposal adds
the option for new MDNs with at least a year’s worth of historical
utilization data to request up to a 3 month supply of addresses.
2. Comments
A. ARIN Staff Comments
· If implemented, staff would require the organization to show a direct
correlation between the demonstrated 1-year utilization rate and the new
discrete network’s 3 month need.
· The policy requires an “applicable 1 year utilization rate� in
order to qualify under this criteria. If implemented, staff would
require that there be at least a full year of utilization data in order
to qualify for a 3-month supply of address space.
· The stated criterion is unclear. Staff would suggest restating as
follows:
o A 3-month supply of address space may be requested if the new MDN can
show a demonstrated one-year utilization history.
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
