dns notify

[AMANI M. BINSEWAIF]

hi,
I am trying to test dns notify, I read rfc1996 and i add the notify yes 
set as per zone but still not  working when i test it between master and 
slave
after I increase the serial no.


zone "xx.ae"{
        type master;
        notify yes;
        file "master/db.xx.ae";
};


messages from logs
Aug 12 11:36:23 ns9 named[21185]: [ID 295310 daemon.info] Sent NOTIFY 
for "xx.ae IN SOA 2" (xx.ae); 2 NS, 2 A



and I want the dns notify to notify only specific ips of slaves server 
not any other slaves  from outside.

Thanks
