What is the official WHOIS website lookup?
https://whois.icann.org/en is the official site, but they don't return records for all gTLDs. For example, it won't show .es domain info, so you need to go to https://www.iana.org/domains/root/db and find out who's responsible for .es, go to their site http://www.nic.es/ and look there. That's why all these third party WHOIS sites sprung up, it's a pain to go different places to look up different gTLDs. If you have a Mac, just fire up Terminal and run whois domainname.com. That uses official WHOIS servers and delegates properly so it should return .es and everything else. More on reddit.com

As someone who works for a registrar, please throttle your whois requests to no more than one per second, slower if you can. More on reddit.com
