      24             :  * This header defines the addr_range class used to handle one range of
      25             :  * addresses (with a 'from' and a 'to' pair of addresses.)
      26             :  *
      27             :  * Also we support CIDR, a CIDR is not a range. A range can define anything
      28             :  * that is not a perfect CIDR match. For example, you could have a start
      29             :  * address of 192.168.10.5 and an end address of 192.168.10.10.
