Is there a way to do a WHOIS lookup search by registrant (the person who owns the domain name) that will return a list of all the domains that individual owns?

Dubious, though you might be in luck if it was a TLD covered by ripe.net

A query like:

jwhois -h whois.ripe.net -- -i admin-c,tech-c,zone-c NIC-12354678

Would return domains where any of the admin/tech/zone contacts were the given person.

That said, there's no single coherent database of domains, each TLD may be administered by a different company and are held on their database; list here: http://www.iana.org/root-whois/index.html

What each of them will provide in response to a whois request is different..

doh, I remember seeing something like this when I was trying to figure out what "firm" snatched up one of my old domains the day I wanted to register it again. They turned out to be one of the nice companies that is tied to one of the firms that will play middle-man to negotiate a transfer deal.

Okay, use the following assumptions:

1) individual owned over 100 domain names
2) all domains registered through GoDaddy
3) you know the individual's name

I don't believe it is possible, for privacy reasons.

Wouldn't a whois search by NIC handle do it?

That only shows the contact information, it doesn't pull a full list of domain names owned.

I have never done a search like that in all the years I have been doing DNS.
I would imagine you would need to persuade a friendly registrar to do it for you.

I've done it but can't recall how. By law it's public information, if you've a valid reason you can request it from the registrar.

They've definitely changed things a lot since I Iast poked around in it.
