[arin-ppml] Revised - Draft Policy ARIN-2022-1: MDN Clarification for Qualification

I weep for my once-pristine Section 8, now increasingly sullied by walls of text, mostly unnecessary.

A complete waste of time as the value of these resources compels more efficient use than this tired artifact language ever did…


So it seems that ARIN will look individually at MDNs, allow them individually to justify transfers, but will impose an Organization-wide cap on using 8.5.7 at a /16 equivalent. If I understand it correctly, I suppose there are some Orgs who would find it easier to justify a transfer when they have MDNs with high utilization levels, but who otherwise can’t meet the 80% threshold as an Organization (or by inference the 50% threshold of 8.5.5). One wonders why they don’t transfer some of their organizationally-unused addresses to their MDNs. I realize 8.5.7 is fractionally easier than 8.5 to process, but still I see this as another seldom-utilized policy and more NRPM clutter. I particularly don’t like the callback to section 4, maybe MDNs should be defined in section 2 instead?

Draft Policy ARIN-2022-1: MDN Clarification for Qualification


Problem Statement:


The requirements for transfers involving companies operating multiple discrete networks under section 8.5 of the NRPM are unclear and need clarification.


Policy Statement:


Replace the first paragraph of Section 8.5.7 with the following:


Organizations may qualify for additional IPv4 address blocks by demonstrating 80% utilization of their currently allocated space. In organizations operating multiple discrete networks, each discrete network may be assessed individually for the 80% utilization threshold. To qualify under this policy, the organization must provide justification that each network is discrete, per the criteria described in section 4.5. Each discrete network must meet the projection requirements in section 8.5.5, and each discrete network for which IP addresses are requested must meet the utilization requirements in section 8.5.6. Organizations may receive one or more transfers up to the total size of their current ARIN IPv4 address holdings, up to a maximum size of /16.


Comments: None


Timetable for implementation: Any
