The WHOIS domain lookup lets you search the global domain registration database known as the WHOIS database to view information about the owner of a domain name or IP address, and the contacts associated with it. Search domain names here to see where the domain lives including what server it's on, registrant and registrar information, and when it will expire.
When you register a domain name, you provide your personal contact information to your registrar who submits this informaiton to the WHOIS database. Once your listing appears in this online directory, it is publicly available to anyone who chooses to check domain names using the WHOIS search. Before you register a domain you should consider how your personal information may appear online when someone performs a whois domain lookup to search this publicly available information.
