In my experience systems/users don't bother to do any sort of authentication or filtering on NTP sources. Most server admins and some implementations do not support authentication either. I'm pretty sure I don't want to get time from just anyone who sends to 224.0.1.1 especially on networks connected to the multicast-enabled Internet. That group address I might note is one I tend to scope at admin boundaries for just that reason. John
