[arin-ppml] Change of Use and ARIN (was: Re: AFRINIC And The Stability Of The Internet Number Registry System)

[Martin Hannigan]

Hi Paul,

It was interesting reading about your problem, your take on matters, the
experience and history with ARIN. Thank you for that.

While I can appreciate ARIN's position from the perspective of 'how do they
know', I can appreciate yours too. We're not talking about criminal courts
and beyond reasonable doubts. Jon Postel's pre RIR legacy assignments are
hand written in a notebook. If that's good enough documentation to
establish legacy assignment then providing "reasonable" proof that an
address was provided for legitimate use would make a lot of sense to me.
However, and admittedly, it's not that simple. Mostly because we don't want
it to be. To some extent, because it can't be. You are a victim of
"progress".

Warm regards, and good luck;

-M<
