Draft Policy ARIN-2014-19
New MDN Allocation Based on Past Utilization

Date: 3 September 2014

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 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.

Timetable for implementation: Immediate
