There are some comments, in the ntp mailing lists, that on dynamic network environments, the following sequence should be used:
1. bring up the network
2. if this is boot time, run ntpdate as soon as possible during boot.
3. run ntpd -qg every so often (like every hour or so).
But I certainly could not see any comments there, nor see any option in 4.2.2, to make ntpd listen on * (and re-scan on a potential IP address change).
