Snow Leopard and mDNSResponder, finally a turn-off
Well. I’ve hunted long and hard for a soft turn-off to the mDNSResponder in OS X broadcasting all sorts of junk all over the place . . .

For anyone who has SSH or ARD (please note, ARD needs to have legacy VNC turned off and only local admin user for authent to keep it secure + required encryption.) this is a nice little security upgrade.
