FQDN looks like another abbreviation that seems complicated to pronounce. It stands for Fully Qualified Domain Name, and let’s clarify what does it means.
What is FQDN (Fully Qualified Domain Name)?
The term “fully qualified domain name”, FQDN for short, sometimes also associated with an absolute domain name, is a domain name that defines its exact location in the tree hierarchy of the Domain Name System. It specifies every domain level, including the top-level domain and the root zone. It is the most comprehensive way to write a particular domain name for a host or a computer.
