If your server allows recursive queries it can be exploited by malicious users. It should be restricted only to ip addresses from your local nets.

To accomplish this, edit your /etc/named.conf and specify in “options” section which ACL are allowed to run recursive queries with allow-recursion option:

# /etc/named.conf
acl localnets { 127.0.0.1; 192.168.0.0/24; };
 
options {
...
allow-recursion { localnets; };
...
};

then restart bind server:

[root@red ~]# /etc/init.d/named restart
Stopping named: .                     [  OK  ]
Starting named:                       [  OK  ]

In Plesk it can be done from the Control Panel:
Server->DNS Settings->DNS Preferences->Allow recursion
and choose localhost or localnets.
