Can you use tcpdump to capture traffic between the dhcp and dns servers 
to see if there are any requests being sent over?

Next step would be strace or enable debugging on the dhcp executable to 
see if it is even trying to do a ddns update.

I guess you've looked at the dhcpd.conf man page, esp the section "THE 
INTERIM DNS UPDATE SCHEME" which explains how it works, but also 
conditions under which it won't do a dns update.

I remember there being some issues adding AAAA records when there was 
already an A record with the same name, or something like that. This was 
mentioned a while back in this list.
