[arin-ppml] Feedback Request: Policy ARIN-2024-6: 6.5.1a Definition Update

Thu Jun 20 13:13:44 EDT 2024

I agree that we should work toward replacing all instances of "ISP" with "LIR"
in the entirety of the NRPM, and then retire 6.5.1a. However, my understanding
was that for IPv4, ARIN staff considered only LIRs that have a physical network
of some kind to be ISPs, and that therefore the 2 terms are not yet treated
identically.

If my understanding is correct, I would propose we replace ISP with LIR
everywhere, and just add a requirement to 4.1.8 that the requesting LIR have a
physical network presence.
