no ADDITIONAL SECTION in answer

[Ulrich David]

Hi,

I try to run an authoritative server only on bind 9.4.2-P2 with a  
mysql-dlz connection.
options {
	directory "/var/bind";
         listen-on { myself; };
	listen-on-v6 { none; };
	statistics-file "/var/bind/stats/named.stats";
	version	"None of your business";
	allow-query { netplus; };
	blackhole { blacklist; };
	pid-file "/var/run/named/named.pid";
};


When I dig on my old authoritative server (bind 9.4.2-p2 without dlz)  
I have an ADDITIONAL SECTION which I d'ont have on my new server :
;; ADDITIONAL SECTION:
dns1.zzzz.ch.	86400	IN	A	15.15.15.1
dns2.zzzz.ch.	86400	IN	A	15.15.15.2
dns3.zzzz.ch.	86400	IN	A	15.15.15.3

In MySQL database I have put all records from the zone, include the A  
record for the dnsX ....

Is there a reason? What I have not understood? :)
