A Fully Qualified Domain Name, FQDN, is a complete domain name which specifies all domain levels indicating its place in the domain hierarchy. It is specific and leaves no room for ambiguity. A Full Qualified Domain Name specifies the host name, the server, and the top level domain, Top Level Domain. For example, www.example.tv is an FQDN with hostname ‘www’, server ‘example.tv’, and top level domain, ‘.tv’.
FDQN specifies domain levels for unambiguous resolution of Uniform Resource Locators, URLs. This can be likened to the file directory system on a computer hard drive. For example, myfile/folder1/folder2/folder3, with folder3 taking the place of a Top Level Domain.
