No, but...
Is there a central/distributed database somewhere that can tell me that this particular IP prefix (say x.y.z.w) has been given to foo AS number? I tried searching through all the WHOIS records for a domain name. I get the IP address but i dont get the AS number.
... if you want to know which AS is originating a prefix which covers a particular address right now, you can always use whois.cymru.com:
[halibut:~]$ whois -h whois.cymru.com 203.97.1.241 ASN | IP | Name 4768 | 203.97.1.241 | CLIX-NZ TelstraClear Ltd [halibut:~]$ Joe
