I am developing a tool where IP to CIDR conversion based on RIR whois data would be useful for implementing filtersets.WHOIS? Alternatively, use the Team Cymru tool to find the AS, then the CIDR Report portal to determine all perfixes originated by the AS in question: http://asn.cymru.com/
Looks like their WHOIS server in verbose mode will do the trick for what I want, as it provides predictable output. Thank you. William
