Run yum update
yum update
Open named.conf file and remove following two lines:
query-source port 53; query-source-v6 port 53;
Make sure recursion is limited to your LAN only. Set ACL. Restart bind to take effect:
rndc reload

If you are DNS server admin, patch your dns server and remove source query port 53 from named.conf file.

It means that your ns do not permit recursive queries from where you test.
