You only need to run one name server. It is both authoritative and =
recursive by default. To limit recursion to only your own IP address =
space add the following option in named.conf
options {
allow-recursion {
192.168.1.0/24;
127.0.0.1;
};
};
Change the address space to suit. Make sure you include localhost.
And after an rndc reload only your internal network will be able to make =
recursive requests.
