RFC 1918 error clarification

Hi bind-users,

I would like to clarify something. I have 14 locations each using a 
private class c address, and a single dns server which I have just moved 
from bind8 to bind9.

I am getting a lot of these:

Aug 17 13:33:13 mail2 named[18610]: client 192.168.16.3#55546: RFC 1918 
response from Internet for 108.21.168.192.in-addr.arpa
Aug 17 13:33:35 mail2 named[18610]: client 192.168.16.3#38729: RFC 1918 
response from Internet for 171.1.168.192.in-addr.arpa

where: 192.168.16.3 is the dns server
and: 192.168.21.108 and 192.168.1.171 are clients on my network

So what I need to do, then, is create a reverse zone file for each of my 
14 internal subnets and reference these in /etc/named.conf, is that correct?

Is there no way I could somehow tell bind to combine all these into a 
single reverse zone file?

(on the old bind8 server, it would add ddns records to a single reverse 
zone file, this must be a bind8 vs. bind9 difference? But I am having 
trouble with ddns updates too and that's a separate question.)

Thanks!
