You can look at Internet routing table collected by Merit. ("http://compute.merit.edu/stats/mae-east/routing-table/"). But the table may mislead you to a wrong ASN if the IP address is an inet-rtr. My suggestion is consulting the table first, and if you think that one IP might be a inet-rtr, consulting IRR using "whois -h whois.ra.net 'address'".
