I'm not going to respond to the rest of this as the two of you have
gotten way off topic. The newsgroup is about NTP and not UDP.

The above makes a basic erroneous assumption aout how autokey works. It
doesn't work the way you think. The IP Addresses are just two
ingredients in creating the protocol, not the only ones. You really need
to read how it works before you criticize what it uses.
