 * Hi! I would like to add IP ranges to the whitelist, but I receive an error “199.27.128.0-
   199.27.135.255 is not a valid ip.”
    I tried to add spaces before and after dash
   but still nothing: “199.27.128.0 – 199.27.135.255 is not a valid ip.” Please 
   help. I can’t go with IP list beacuse it has enormous size (251040 addresses).
 * Why CIDR is not supported?

    Below is a nice video
   telling you how to do it: [http://ithemes.com/tutorials/getting-started-ithemes-security-part-5-banned-users/](http://ithemes.com/tutorials/getting-started-ithemes-security-part-5-banned-users/)
   basically you would do this: 199.27.128.0.* this will block everything in the
   range 199.27.128.0 and up. hope this helps, Tony States
