Hi John,

Plurality in a steady state system is easily understood.

Address management is anything but a steady state system. What do you
do when your ARIN region customer with the /19 closes his account,
dropping your ARIN-region presence to 15%? Plurality applied to such a
dynamic system is just begging for trouble.

Fair point. Any absolute amount applied to the dynamic system that is
address management is begging for trouble. Plurality just happens to
be more confusing than most.

Well, I don't agree with that at all. The regionalized registry system
makes no sense unless the overwhelming majority of the addresses used
within the ARIN region come from ARIN and the overwhelming majority of
the addresses used within the RIPE region come from RIPE. The idea
that a multinational registrant might get his addresses from RIPE and
then deploy half of them in North Carolina just doesn't make sense.
Deploying addresses outside the region should be the exceptional case;
if the majority of your addresses are deployed outregion, you're doing
it wrong.

Moreover, the law enforcement objective *is not served* if RIPE region
addresses registered to RIPE region entities are deployed in the ARIN
region where law enforcement has jurisdiction.
