Are you serving time to other systems? If not, it's not needed.

You were querying this server, yet that's the address in here, so I'm
not sure what you were getting.

There is no default. The address is required. Do you have a multicast
server set up somewhere? Otherwise this  option has no meaning and since
you didn't disable authentication it will in any case ignore any
multicast packets that it does receive even if it were configured properly.

On a LAN why would you put this in at all? This should not be here
unless you have a good measure of the propogation delay AND ntpd is not
doing its own calculation because it is not querying the multicast
server at all (it's part of what authentication would do for you).
