The unique name that identifies a specific Internet location. See also domain name.

The unique name of a network entity, consisting of a hostname and a domain name that can resolve to an IP address. For example, "www" is a hostname, "c2.net" is a domain name, and "www.c2.net" is a fully-qualified domain name.

Domain names reflect the domain hierarchy. Domain names are written from most specific (a host name) to least specific (a top-level domain), with each part of the domain separated by a dot '.'. A fully qualified domain name (FQDN) starts with a specific host and ends with a top-level domain. An example of this could be: Name Type engarde.guardiandigital.com FQDN engarde Machine Name guardiandigital.com Domain Name com Domain

A fully-qualified domain name (FQDN) includes all parts of a domain: the hostname or subdomain, the domain name, and the top-level domain. They are often seen in the URLs for websites (e.g."http://support.microsoft.com").

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.
