The following example defines two access control lists and uses an
options statement to define how they are treated by the nameserver: 

acl black-hats { 10.0.2.0/24; 192.168.0.0/24; };  
acl red-hats { 10.0.1.0/24;  }; 
 
options {     
	blackhole { black-hats; };     
	allow-query { red-hats; };     
	allow-recursion { red-hats; };  
}    

This example contains two access control lists, black-hats and red-hats.
Hosts in the black-hats list are denied access to the nameserver, while
hosts in the red-hats list are given normal access.
