How to Stop Recursion DNS

[tipwebs]

A DNS query may be either a recursive query or a non-recursive query. If recursion is set to 'yes' (the default) the server will always provide recursive query behavior if requested by the client (resolver). If set to 'no' the server will only provide iterative query behavior. If the answer to the query already exists in the cache it will be returned irrespective of the value of this statement. This statement essentially controls caching behavior in the server.

For disabling it, Open named.conf file and make sure following settings exists under Options { ... } settings:

options {
...
allow-transfer {"none";};
allow-recursion {"none";};
recursion no;
...
};

Now restart the named service.
