Allow CIDR notation for Security/Ban Control
Currently there are only two ways to ban IPs:
- Ban an individual IP
- Ban an entire block of 256 IPs using 123.34.56.* or 65,356 IPs using 123.34.*.*
Request that CIDR notation ( http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing ) be added as a method for banning IP blocks, as this allows for a more flexibility in managing which IP addresses are banned.
