  Rewritten with IPv6 support by
  .An Eric Jackson Aq ericj@monkey.org .
  .Sh CAVEATS
! UDP port scans using the
  .Fl uz
! combination of flags will always report success irrespective of
! the target machine's state.
! However,
! in conjunction with a traffic sniffer either on the target machine
! or an intermediary device,
! the
! .Fl uz
! combination could be useful for communications diagnostics.
! Note that the amount of UDP traffic generated may be limited either
! due to hardware resources and/or configuration settings.
