I had thought new allocations are based on demonstrated need. The fact that addresses are in use would seem to suggest they're needed. As I've said, I haven't been following ARIN's policy discussions -- can you point me to the policy that says allocations can be denied because you happened to have (demonstrably ill-advisedly) used the wrong bit patterns in setting up your network?

The problem is that "in use" means different things to differnet

ifconfig em0 inet

I'm now using 16 million IP addresses at home.  ARIN policy does
not allow me to get 16 million public IP addresses as a result,
based on the 1 machine I have configured at the moment.

In the case at hand we don't know if the original poster configured
up /16's on p2p links for two hosts each, or if they have an actual
host up and pingable at every single IP address.  ARIN has a duty to the
community to ask these questions, because otherwise anyone could
fabricate a "need" for as many addresses as they want.

It would seem the original poster and ARIN have a disagrement in this
case as to how many IP addresses are required to support their needs.
Perhaps incomplete information was provided, perhaps ARIN staff got it
wrong.  No one on NANOG has enough information to know either way.
