This will check the Shared Registry System to see if a domain has been registered. Under the Shared Registry System, several organizations (known as registrars) register these domains. This will first check the Shared Registry database, and then get specific information from the database of the organization listed as the Registrar. For all other supported domains, it will retrieve all information available about the domain from the appropriate registry.

Enter the domain to check, including the extension (.com, .net, .org, etc.), into the field below and press return to search the whois database.
