What does the acronym FQDN stand for?

The acronym FQDN stands for Fully Qualified Domain Name. This term is used in the context of internet addressing to refer to a complete domain name that specifies its exact location within the Domain Name System (DNS). An FQDN provides a precise path to a specific host or resource on the internet, eliminating any ambiguity. It comprises two main parts: the hostname (the specific name of the host) and the domain name (the broader category in which the host resides). For example, in the FQDN "www.example.com," "www" is the hostname and "example.com" is the domain.

Understanding FQDNs is vital for system administrators and IT professionals, as they are used for various networking purposes, including web requests, email routing, and server identification, ensuring that resources can be consistently accessed over the internet.
