[arin-ppml] Request for Feedback: Draft Policy ARIN-2024-8 Restrict the Largest Initial IPv6 Allocation to /20

[David Farmer]

/16 is a reasonable limit; keep the current NRPM. One /16 allocation in
nearly a decade does not concern me. /16 allocations were intended to be
rare but possible; in fact, I believe the policy is functioning as
intended. If we see several additional /16 allocations in the next couple
of years, I could be convinced to reconsider my position. But at this
point, I think this policy is premature.

Thanks
