What is FQDN used for?
FQDN – What does it stand for?
A domain name that specifies its precise location inside the Domain Name System’s tree hierarchy is referred to as a “fully qualified domain name,” or FQDN. It is occasionally also used in conjunction with an absolute domain name. So, it describes each domain level, including the root zone and Тop-Level Domain. It is the most thorough method of composing a specific domain name for a host or machine.
