Check /etc/named.conf for recursion restrictions

The top of your named.conf should look something like:

include “/etc/namedb/rndc.key”;

controls {
inet 127.0.0.1 allow { localhost; } keys { “rndc-key”; };
};

acl “trusted” {
127.0.0.1;
};

options {
pid-file “/var/run/named/named.pid”;
directory “/etc/namedb”;
dump-file “/var/dump/named_dump.db”;
statistics-file “/var/stats/named.stats”;
version “BIND”;
allow-recursion { trusted; };
allow-notify { trusted; };
allow-transfer { trusted; };
forwarders { 127.0.0.1; };
};
