The tricky part is in converting a domain name of a
primary nameserver to IP addresses,  when the IP
addresses of the primary nameserver changes.

If the primary nameserver ask DNS its IP address
to send an update request to itself, it will get
old addresses.

What if primary.childzone.parentzone.example.com
is the primary for parentzone.example.com,
and childzone.parentzone.example.com?

Another problem is lack of redundancy that, when the
primary server is down, dynamic update is impossible.

My point is that configuring lengthy random string of
security key is more painful than configuring addresses.
