No, that subnets the entire world. The commas are effectively "OR" statements, so just this part: [!192.168.1.222,!192.168.1.223] will match any IP address. Anything that is not 192.168.1.222 <http://192.168.1.222> OR anything that is not 192.168.1.223 <http://192.168.1.223>. The first clause will match all IPs except 192.168.1.222 <http://192.168.1.222>, and the second clause will match 192.168.1.222 <http://192.168.1.222>, among many others. The net result is everything. Is there solution/expression that matches the "given subnet except given list of IPs" ?No, other than adding up other subnets to create the equivalent.Are there IP RANGES, like [IP-IP] or maybe [IP:IP] ?
