Use the following form to perform a query exclusively on the InterNIC database (which includes the ".com", ".net", and ".org" top level domain names). Not only can you determine whether a domain name you desire is already in use, but you can find contact names, e-mail addresses, postal addresses, and telephone numbers. Simply enter the appropriate identifier (such as a domain name, NIC handle, etc) in the entry field below and select the "Check availability" button.
