Alternately, you could define the "allow-recursion" and "version"
options:
options { directory "/etc/namedb";
version "none.of.your.business";
pid-file "/var/run/named.pid";
listen-on { localhost; YOUR_IP; };
query-source address YOUR_IP port 53;
transfer-source YOUR_IP;
allow-recursion { localhost; YOUR_SUBNET; }; };
