I need to debug my DNS and the best way to do so is via logging. Therefore:

[root@cmlin02 ~]# vi /etc/named.conf

...

logging {
  channel "default_syslog" {
    #syslog local6;
    file "/var/log/named/named.log" versions 3 size 5m;
    severity debug;
  };

  category default { default_syslog; };
  category general { default_syslog; };
  category config { default_syslog; };
  category security { default_syslog; };
  category resolver { default_syslog; };
  category xfer-in { default_syslog; };
  category xfer-out { default_syslog; };
  category notify { default_syslog; };
  category client { default_syslog; };
  category network { default_syslog; };
  category update { default_syslog; };
  #category queries { default_syslog; };
  category lame-servers { default_syslog; };
};
...

[root@cmlin02 ~]# service named restart
