ARIN-prop-211 New MDN allocation based on past utilization
Proposal Originator: Jason Schiller
Date: 20 August 2014
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.
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 18.104.22.168 unless the organization can demonstrate additional need using the immediate need criteria (22.214.171.124).
Upon verification that the organization has shown evidence of deployment of the new discrete network site, the new network(s) shall be allocated the largest of the following:
- the minimum allocation size under section 126.96.36.199
- more than the minimum if the organization can demonstrate additional need using the immediate need criteria (188.8.131.52)
- 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
