Fully Qualified Domain Name (FQDN)

Fully Qualified Domain Name (FQDN) 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 unambiguity; it can only be interpreted one way.
