It would be achievable for a stealth master. If I was
doing it I would have the stealth master send signed notifies
periodically, similar to the dialup master, and have the
slave accept the notify if the signature was correct and
save the source address for the refresh query. Only notifies
would trigger the refresh check similar to dialup.
I would not have a dynamic host listed as a nameserver.
I'm assuming, in saying this, the dynamic host is dropping
off the net and the address is potentially being re-assigned,
not that ISP is play stupid DHCP games by re-assigning a
new address every time the lease expires. Even this it
could be problematic as the DNS was designed with stable
nameserver in mind.
If you are going to do this grab a 9.2 snapshot and work from
it.
