A fully qualified domain name (FQDN) is a complete and precise name that locates a specific entity on the internet. It includes the hostname and the domain name, and it’s part of the Uniform Resource Locator (URL) system. FQDNs enable every connected object on the internet- computers, servers, and other entities- to be identified and located within the framework of the internet.
You can find the FQDN of a website through the terminal on MacOS and Linux or advanced system settings on Windows. FQDNs are essential since they enable the DNS (Domain Name System) to locate and translate domain names into IP addresses. DNS functions as the internet’s address book.
FQDNs have a trailing period that follows the Top-Level Domain (TLD) on their right. This period signifies the root zone of the unnamed domain. However, modern software, including internet browsers, processes the final period automatically. The root zone of the unnamed domain represents the internet.
The FQDN designates the unique location of an entity within the Domain Name System hierarchy. It communicates the position of a host concerning the root of the DNS namespace. FQDNs are essential since they enable every entity on the internet to be uniquely and accurately identified and located.
