I would have liked to see how well the RIRs are at recovering unused ASNs, if at all. For example ARIN has a 30 day policy: http://www.arin.net/registration/templates/asn-request.txt Do the RIRs *ever* revoke an ASN after the customer does not follow the RIR stated rules? Would love to see numbers on that issue. No wonder the ASN pool will expire in 2010. -Hank

geoff,
why not assume o all speakers will not transition at the same time, but o before the first > 0:xxxx is issued/used that all will transition?
i would think this is operationally viable.
