[arin-ppml] Draft Policy ARIN-2024-5: Rewrite of NRPM Section 4.4 Micro-Allocation

Thu May 23 11:56:38 EDT 2024

I'm torn.

On one hand, it doesn't matter. The purpose of the NRPM is to regulate
*Internet* networks so it's not a hard leap of faith to understand (legally
or otherwise) what 4.4 serves especially with the two specific subsections
for exchanges and root ops.

On the other hand, some room for staff to maneuver this small piece might
be wise.

If someone has a use case, all ears. The usual suspects, nuclear power
plants, traffic lights, DHS CSI networks, SOSUS, SS7/SS8, etc. don't seem
to fly.

+ / - overall.

Thanks,

-M<
