Hi all, Just to clarify: my earlier mention of “ISP (LIR)” or a glossary note was never meant as a permanent dual-term solution. I agree that the end state should be LIR everywhere in the NRPM, to align with global terminology and reduce ambiguity.
My concern is the transition. Many members are still used to “ISP” in ARIN policy language. A simple first-reference note and glossary mapping (“ISP = LIR in ARIN context”) would give people a smoother on-ramp while ARIN phases out the older term. This way we get to the same destination—LIR consistently in policy—but with less confusion along the way.
