What does FQDN mean?

Fully Qualified Domain Name (FQDN), also referred to as an absolute domain name, is a domain name that specifies its exact location in the hierarchical structure of the Domain Name System (DNS).
FQDN provides a unique and absolute address for a specific resource on the internet.

FQDN mostly consists of three levels:
Hostname: The hostname is the leftmost part of the FQDN and is often used to specify a particular service or resource within a domain. In the example "www.fullforms.com," "www" is the hostname, which often represents a web server.
Domain Name (Second-Level Domain): The domain name is placed in front of the Top-Level Domain (TLD) and provides the broader context or organization to which the resource belongs. In the example, "fullforms" is the domain name (second-level domain).
Top-Level Domain (TLD): The TLD is the rightmost part of the FQDN and is the highest level in the DNS hierarchy. It often indicates the type or purpose of the domain.
Common TLDs include .com, .net, .org, and many others.

www.fullforms.com is an FQDN, where www is the hostname, fullforms is the domain name, and .com is the Top-Level Domain (TLD). This structured format helps in specifying the exact location and type of resource on the internet or within a network.
