Never attribute to malice that which can be adequately
explained by stupidity.

I could have assumed that you had evil intent in this
slur against SBC and other list members, but instead
I applied Hanlon's razor and assumed the other.

There is plenty of data as to how humans react to threat.
If ARIN did resort to threats regarding IPv4 addresses,
many organizations would leave ARIN (flight) and many
others would launch lawsuits (fight). Let's not bother
with an experiment because it wouldn't improve the

And you END with the Mr. Nice Guy approach because the law
of diminishing returns tells you that vinegar ain't worth
the trouble. And as for RAID, that is more likely to harm
your health (and that of your kids) than to reduce the fly
population. Good construction techniques and steel mesh
window screens (not plastic) will keep out more flies than
RAID can kill. 

So what is the ARIN analogy of the window screen? Maybe the
use of IPv6 addresses to ward off the need to deal with IPv4
depletion issues.

It has already happened. Bill Manning started reclamation about
10 years ago, and at this point, there isn't much left except for
the Defense address ranges but even there, it takes a lot of effort
to get a huge bureaucratic organization to agree to something that
is not threat-related.

Now there is an interesting comment. Because it implies that ARIN
might get some significant aggregate results by mandating that 
RSA signers all do internal audits and report back to ARIN. Right
now the responsibility for IP addressing in most companies is spread
out and scattered. There is no single point of authority in the senior
management team (or thereabouts). If ARIN required RSA signers to do
a serious addressing audit signed off by the CFO of the company, that
would shake things up a bit.

In fact, such an audit requirement would probably extend the lifetime
of IPv4 at least a few more months by shaking loose a lot of available
addresses within a company.
