We don't know, this is why the NRPM has section 3.6.1 which is currently
pending implementation - basically the ARIN staff is figuring out how
to do it. They have sent many mails out already and it's my
understanding that they have discovered a lot of abandoned stuff as
well as a lot of stuff in use that has stale data on it - which is
being corrected as they inform holders.
So far there has been one presentation from ARIN staff on this effort
which boiled down to (in my humble opinion) a statement that the
task was way, way larger than they figured it would be. I should
add as one of the 4 authors of that policy my surprise was that the
ARIN staff DIDN'T think it would be a monumental task.
The AC basically gave them a year to figure something out. I personally
wrote an outline of how I thought they should be going about doing it
(ie: go after the low hanging fruit first) but I never heard back as to
the results. The discussion on the mailing list that proceeded from
the policy proposal also had plenty of ideas as well on how to go about
They probably are not too pleased with me though, as I initiated this
back in Aug 2008 with a proposal titled "whois POC e-mail cleanup"
which was later combined with 4 other later proposals and retitled -
my initial proposal was sufficiently unworkable that it stimulated
a second proposal 3 days later titled "annual WHOIS POC Validation"
and that led to both to be combined with 2 other proposals to create the
result that was eventually passed.
