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).
Description
It specifies all domain levels, including the top-level domain and the root zone.
Unambiguous
A fully qualified domain name is unambiguous: it can be interpreted only in one way.
DNS root domain
The DNS root domain is unnamed, which is expressed by the empty label, resulting in a fully qualified domain name ending with the dot character.
Origin
The need for fully qualified domain names first arose out of a requirement for uniformity as the Internet was quickly growing in size in the 1980s.
