15776 in my BGP address tables, 30,000 or so assigned or allocated (IANA
isn't talking to me this morning...).

Exhaustion looks to be about one doubling away, with a doubling time
of ~ 5 years.

So you might be able to recover 50% if you were very aggressive, which would buy
you 3 years or so, which I regard as highly optimistic.

I suspect you would have a hard time getting back any ASN currently in use.
