How to disable the recursive queries to Nameserver (DNS)?

[kaustubh_s]

If DNS tools like intodns.com gives following warning for the nameservers configured,

I could use the nameservers listed below to performe recursive queries. It may be that I am wrong but the chances of that are low. You should not have nameservers that allow recursive queries as this will allow almost anyone to use your nameservers and can cause problems.

then you can disable recursive queries to your nameservers in the following way,

Put either of the following codes in option section of the /etc/named.conf

allow-transfer {“none”;};
allow-recursion {“none”;};
recursion no;

OR

allow-recursion {localnets ;};

Save and quite named.conf and restart nameserver service (/etc/init.d/named restart)
