Closing open DNS

[ephigenie]

yeah but thats not a good idea - because then your local server is not able to answer queries to the server itself. (beyond the authoriative zones) But thats often a must because isp's dns server are sometimes quiet unreliable.

I'd recommend putting this into your named.conf.options

Code:

acl local {
        127.0.0.1;
        <your-ip>;
        };

allow-recursion { local; };

and use the isp/ providers dns as forwarders if needed.
