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 "Query" button.
The default action (unless directed otherwise by entering a specific domain name or NIC handle), is to do a very broad search, looking for matches in all types of records and most fields (name, nickname, hostname, net address, etc) in the database. For more information, enter "help" in the entry field above and select the "Query" button.
