fully qualified domain name (Internet) (FQDN)

A Fully Qualified Domain Name (FQDN) is a complete domain name with service specification, which has an entry for each domain level, from the third level domain or subdomain, through the second level domain to the Top Level Domain( TLD).

In the case of the domain name www.e-books.itwissen.info, the Fully Qualified Domain Name (FQDN) consists of the top level domain "info", the second level domain "itwissen" and the third level domain "e-books". For larger organizations, the complete FQDN is usually not required to address a single person, since such organizations operate on higher domains with gateways.

With ENUM (Telephone Number Mapping), the regular telephone number is derived from the FQDN address, or conversely, the FQDN name is generated from the telephone number.
