recursion no setting

What file do I want to put the recursion no statement in on a dns server

 

If you use Debian/Ubuntu, it's /etc/bind/named.conf.options:

Code:

options {
        directory "/var/cache/bind";

        // If there is a firewall between you and nameservers you want
        // to talk to, you may need to fix the firewall to allow multiple
        // ports to talk.  See [url]http://www.kb.cert.org/vuls/id/800113[/url]

        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.

        // forwarders {
        //      0.0.0.0;
        // };
        allow-recursion { none; };
        auth-nxdomain no;    # conform to RFC1035
        listen-on-v6 { any; };
};
