What is FQDN?

FQDN stands for Fully Qualified Domain Name. It specifies the exact location of a host within the Domain Name System (DNS) hierarchy. It includes all domain levels, including the top-level domain (TLD) and the hostname. For example, 'www.example.com' is an FQDN. FQDNs are crucial for uniquely identifying and accessing resources on the internet, as they provide a complete and unambiguous path to a specific server or service.
