"Service Area: Networks BGP-announced on the DIX"
Since the intended (and announced) use of this server is just for DIX
networks, blocking NTP from any other networks should be trivial. That
IP address will still be hit by D-Link devices looking for a suitable
server, but with no response, they'll move onto another device, and
probably never try the DIX address again, at least until they're
rebooted. That alone should kill off 95% of the unwanted traffic
hitting the box, and probably 80% of the traffic even being sent to DIX
in the first place.
