Fully Qualified Domain Name (FQDN)

A fully qualified domain name (FQDN), sometimes also referred to as an absolute domain name or FQDN hostname, 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 (FQDN) example: sub.domain.com

To put it in simpler words, a FQDN is a hostname with 2 “.” (dots), like a subdomain.
