How to Search Domain Names By Owner

Searching for the owner of a domain name is relatively easy. This type of search, known as a "whois" search, is offered by many online look-up services at no charge. Searching for the owner's name to find all domain names owned — known as a "reverse whois" search — is much harder to come by, but it is available. You can get preliminary results for free, but there is a charge to retrieve a full set of domain names for a given owner.
