[W/K] :: fully qualified domain name

  fully qualified domain name
       
           (FQDN) The full name of a system, consisting of
          its local hostname and its domain name, including a
          top-level domain (tld).  For example, "venera" is a hostname
          and "venera.isi.edu" is an FQDN.  An FQDN should be sufficient
          to determine a unique Internet address for any host on the
          Internet.  This process, called "name resolution", uses the
          Domain Name System (DNS).
       
          With the explosion of interest in the Internet following the
          advent of the World-Wide Web, domain names (especially the
          most significant two components, e.g. "sun.com", and
          especially in the ".com" tld) have become a valuable part of
          many companies' "brand".  The allocation of these, overseen by
          ICANN, has therefore become highly political and is
          performed by a number of different registrars.  There are
          different registries for the different tlds.
