Fully-qualified Domain Name



A fully-qualified domain name (FQDN) is that portion of an Internet Uniform Resource Locator (URL) that fully identifies the server program that an Internet request is addressed to. The FQDN includes the top-level domain name, the second-level domain name and any other levels. An FQDN should be sufficient to determine a unique Internet address for any host on the Internet. The prefix "http://" added to the fully-qualified domain name completes the URL.
