How do you justify saying they've been doing anything wrong? Nothing in 
policy says that its wrong.  The only thing in policy, says is ARIN's 
primary role is issuing resources for use within the region.  So that 
means out of region use is a secondary role in my opinion.  The only 
justification for any regional limitation I can theoretically come up 
with, is that the stress on the system created by uneven IPv4 run-out 
among the RIRs is creating a temporary conflict between these primary 
and secondary roles, and only for the remaining IPv4 free pool 
resources.  And to be honest, I'm not sure that is really sufficient 
justification to change the rules, or that any change can be effective 
to prevent the problems created by the uneven run-out among the RIRs.

I think if we are to make any restrictions, they should apply only to 
new IPv4 resources from the free pool and not be retroactively applied 
to old resources even if they are recovered in the future, or for any 
transferred resources.  But, I'm still not convinced any restrictions 
are needed or justified even because of IPv4 run-out, and I'm even less 
convinced they can be effective without significant collateral damage.

We (globally) created a run-out scheme that was going to be uneven. 
There was at least one rejected proposal that tried to even out the 
run-out across the RIRs.  Unfortunately, I think we just need to live 
with the consequences of our actions, or inaction in this case.

It's not unilateral action, its been the norm all along.  The RIR system 
is intended to be facilitatory, not restrictive.  AfriNIC and LACNIC 
have diverged from the norm by putting in place regional use 
restrictions.  I'm not saying there wasn't reasons, or that they did 
anything wrong, but that was not the norm previously.

Please read what Geoff Huston say at the NANOG 59 PPC, toward the end of 
the following section;

As the problem statement says, I think the real problem is that policy 
is ambiguous on the subject of out of region use.  Which means there are 
some in the community that think out of region use is outside the rules, 
as you seem to think.  Then others think it is perfectly normal and has 
always been allowed, because its never been disallowed in policy.  I 
think we need to clarify that out of region use was always intended to 
be allowed by policy.

Thanks.
