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
