Hi Owen,

You're wrong-ish. "Address leasing" is not prohibited per se, it just
doesn't count as in-use for the utilization requirements.

Consider Amazon AWS. You can have an "elastic IP address" that's not
attached to a running server. If it stays that way for most of the
month, they charge you for it explicitly rather than wrap it up in the
general server charge. In other words, they lease the address without
any associated connectivity.

Is that address in use per ARIN policy? I don't think it is. Has ARIN
ever asked Amazon to detail the number of elastic IP addresses that
are not actually in use when it sought more addresses? Probably not.
Should they have? Only if there's reason to believe that there are a
large enough number of such addresses to make a difference. Otherwise
it's purposeless paperwork.

Bill Herrin
