how to match client_addr to one class with variable subnet netmask

Hi, All

 

One simple question, customer had one class like below:

 

class special_sub {

 

10.1.1.0/24

 

10.1.2.0/24

 

11.0.0.0/8

 

12.1.0.0/16

 

}

 

How can we use irule to match client_addr to this class.

 

 

Best Rgds,
