When I returned an ASN 2 months ago to RIPE, I asked what the procedure
was to deallocate an AS object and return it to the pool of available
numbers. I was told there was no procedure since I was the first.
Not quite the same thing and not the same registries Hank. Check the PIER
wg archives. There is a method to return IPv4 prefixes. ASN return is a bit
different but does work with InterNIC.
