That seems to be the closest to a complete db, but I noticed it doesn't necessarily have the same info as ARIN. For example ARIN's listing for 1239 has a lot more details than the RADB entry.
From the responses so far, it seems that it is necessary in some cases to query ARIN, RIPE, and APNIC to find the info you are looking for.

I usually use radb as it seems to referance other whois servers:
whois -h whois.radb.net as1221

I've always used whois.arin.net to check ASN registrations, and until now it's always had information on those that I've checked. It doesn't have anything for 1221, which according to route-views.oregon-ix.net is Telstra. Is there a single complete database that has ASN assignment info?
