Dear Matus / Tony, I understand your point.
It is good practice to be authoritative for non routing prefixes so 
queries are not sended outside.
About RFC 1918 , I understand it is necessary to provide reverse mapping 
for non - internet routing prefixes as described here:
My idea for this is to add an empty  zone for the,, and prefixes.
In my case my local network is configured on so I will also 
set a zone for this.

For RFC /3330/5735  can not find information. Could you provide?

I have also included zones for RFC1912 (they were already on the 
named.conf template) with deals with loopback resolution and reverse 
Other question :
For an ISP , is it mandatory to provide reverse mapping for the public 
prefixes I have assigned?

Thanks in advance,
