OK thanks... I've used whois before, but yeah the output has been a bit confusing to me. I think I usually use it with a host name, and using it with an IP gives different info.
I am interested in how the databases that 'whois' queries are populated... the Wikipedia page looks like it will have some good pointers.
- yourad_io 12y agoYou may also be interested to know that this database is open[1]: > We produce daily snapshots which are available to the public. You can find these files at our FTP site at: ftp://ftp.ripe.net/ripe/dbase/ripe.db.gz > or split by object type at: ftp://ftp.ripe.net/ripe/dbase/split > These daily snapshots exclude the object types: person, role, organisation and mntner. For data protection reasons, personal data is not available in bulk format. [1] To avoid confusion, that isn't just Europe (whose Regional Internet Register is RIPE NCC) but contains other continents/RIR data.

- justin_ 12y ago> I am interested in how the databases that 'whois' queries are populated As rid mentioned in his comment, this information comes from RIRs, who assign IP ranges to companies and other groups that request them. The WHOIS database is simply updated when an IP prefix is created or updated. When you make a WHOIS query, the RIR server is automatically contacted and the server simply returns a plaintext reply containing all the relevant information. For example, ARIN (the North American registry) has a whois server for looking up data on IP addresses set up here: http://whois.arin.net http://whois.arin.net
