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 tree hierarchy of the Domain Name System (DNS). Usually an FQDN consists of a host and domain name, and a Top-Level Domain (TLD). FQDN provides enough information so that it can be converted into a physical IP address. FQDNs are used to specify the exact location of a webpage or webserver to a client.
A FQDN is mostly consist of three levels:
1) The appendage of the domain is the Top Level Domain (TLD). Example: com, net or org
2) The domain name will be inserted in front of the TLD. Example: companyname or websitename
3) At the very first stands the hostname. For webpages mostly: www
For example, www.fullforms.com is a fully qualified domain name, where www is the host, fullforms is the second-level domain (domain name), and .com is the Top Level Domain (TLD).
