Question by The Commissioner: How do you search the WhoIs database?
I am trying to figure out how to research the WhoIs database to see who how many domain names, and which ones, to which a person or entity is registered?

For example, I’m trying to figure out how many domain names are registered to John Doe. I’d like access to the WhoIs database so I can search for all sites that have the registrant John Doe and have a list returned to me.

I know I can enter a website, like www.OneMonthFree.com, into a domain registration firm like GoDaddy and use their WhoIs database to find out the registrant of a specific domain, but there are some 59 million .com sites and I really don’t have that much time. I want to reverse that process and research on name or address or phone number or other searchable field.

Naturally, I’d like to search for free, but pay sites are OK.

Question by SearchSleuth: How can I perform a whois search by registrant name?
Doing some competitive research, but my key competitor put their domains on several IPs. I did a reverse IP lookup, but there are a bunch of other domains along with them (using shared hosting, I suppose).
I do know that they use 3 variations of the same registrant name. Is there any tool or method by which to query whois databases for that information?

Even thought it appears that the registrant data goes out to all the whois servers, it seems that none of the Whois offerings give you the option of searching against that field. Maybe some of the original command-line tools let you do this?

Here is one service that lets you search for registrant ID within the *.us domains: http://www.whois.us/.

Question by kroyte: If I am the WHOIS contact for a doman, am I the owner of the name?
My registrar says the domain expired in January and wants to charge me 0 to reclaim it. But WHOIS lists me in all three places, and says that domain is registered until January 2008.

well, its one of two things

either, they say that and hope you’ll register it for the first time :p

or the credit/consumer records they are using to contact you are flawed, and its registered to some1 with the same name, but not you

Question by haadyagob: My domain name has expired but my details are still on Whois?
I paid my subscription 2 weeks after it expired and now some anonymous person is using it. My domain provider won’t answer my letters or emails. Should I just give up on this and just register a new domain name and cut my losses?
http://domains.whois.com still shows MY details as domain owner. Other WHOIS sites says someone else. Confused!

You should still be able to contact the new domain owner through their proxy.
