What is an FQDN? Definition, Examples, and Importance

FQDN stands for Fully Qualified Domain Name. It is a complete domain name that fully specifies its owner, location, and hierarchy. In other words, it is a domain name that includes all of its subdomains and labels from the root label to the leaf label.

For example, in the domain name "example.com", "example" is the FQDN because it fully specifies the domain name and its location within the hierarchy of the internet.

FQDNs are used to uniquely identify a computer or device on a network and are essential for email delivery, web hosting, and other network services. They are also used to verify the authenticity of a website or service, as well as to enforce security policies and access controls.
