title: Get FQDN of workstation client application is running on
body: <p>I'd like to know the way to get FQDN of workstation client application is running on. I've tried <code>HOST_NAME()</code>, but it returns only the left part.
  I've found out, that <code>sys.dm_exec_connections</code> is rather useful, but there is only client's workstation IP address, no FQDN.</p>
