Well, if you really want to learn about the NTP servers a target is using
you can always just sent them a regular NTP timing query (mode 3) and just
read off the IP address in the reference ID field of the response (mode 4).

Unless the server is an IPv6 server.  This trick only works for IPv4.

And we have a fix for all of this that will be out soon.
