No, they have nothing directly to do with each other other than the same owner.

Chopper3 is absolutely correct, however you can try a "Registrant Search" and maybe see some of them. The problem there is most services will not give you EVERY registered site if a company has registered 1,000,000 sites. It also depends on the name of the person who it is registered under; if they're not all registered under the same "name" (in Google's case the name is the informative "DNS Admin") so that can change.

Some Whois lookup sites offer this information as a premium service, but it by no means is a comprehensive list. I think it is based on collecting Whois and DNS data and then grouping it by IP address. Here is a link to a "reverse IP lookup" for the domain, but it will cost you around $15.00 per month to access.

If you have an IP to start with, apparently Bing can help you.
