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; }; };
