A fully qualified domain name (FQDN), sometimes also
referred to as an absolute domain name, is a domain name that
specifies its exact location in the tree hierarchy of the Domain
Name System (DNS). It specifies all domain
levels, including the top-level domain and the root zone. A fully
qualified domain name is distinguished by its lack of ambiguity: it
can be interpreted only in one way. It usually consists of a host
name and at least one higher-level domain (label) separated by the
symbol “.” and always ends in the top-level domain.
