IP Deny Manager

This feature will allow you to block a range of IP addresses to prevent them from accessing your site.

Valid examples of how you can block IPs (CIDR Format):
10.5.3.113 - will block only IP 10.5.3.113
10.5.3.0/24 - will block all IPs in range from 10.5.3.0 to 10.5.3.225
10.5.0.0/16 - will block all IPs in range from 10.5.0.0 to 10.5.255.255
10.0.0.0/8 - will block all IPs in range from 10.0.0.0 to 10.255.255.255
