      When ntpd is starting up it seems to try and listen on all interfaces, and both IPv4 and IPv6. In my example system there is no IPv6 and it logs a whole bunch of "fails: Can't assign requested address" messages.
      It does no harm, but is just noise in the log, and the word "fail" can make users think there is a problem.
      Probably do not care - but if it is easy to fix then why not.

      Sample ntpd log:

      Nov 28 08:03:34 	ntpd[60859]: Listening on routing socket on fd #48 for interface updates
