Here is my named.conf file which may help you solving my problem

 

################named.conf on server1.guru.com########################

 allow-recursion { 192.168.0.0/24 ; localhost; };
};

controls {
 inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};

logging {
 category dnssec  { security_log; };

I think you must allow dynamic updates by "allow-update" or "update-policy"
in bind's zone-files...

And one more thing: for every ip from your dyn-ip pool I would
set very short ttl/expire in your zone-files. Otherwise caching-clients
would get know too late, that there was a change in ip/dn assignment...
