Open DNS Servers

I've tried everything under the sun to try and close the open dns server issiue on my box but nothing seems to fix it.

Here' what my named.conf looks like...

----------------

controls {
inet 127.0.0.1 allow { localhost; } keys { "rndckey"; };
};


acl "trusted" {
1.2.3.4; 2.3.4.5; 127.0.0.1;
};

options {
directory "/var/named/";
allow-transfer { IP's that are allowed (slaves/master);
// query-source address * port 53;
version "not currently available";
allow-recursion { trusted; };
allow-notify { trusted; };
allow-transfer { trusted; };
};
