This feature will allow you to block a range of IP addresses to prevent them from accessing your site. You can also enter a fully qualified domain name, and the IP Deny Manager will attempt to resolve it to an IP address for you.
You can perform this action by visiting IP Blocker from cPanel.
These are the formats that you can use to block the IP addresses:
Single IP Address 192.168.0.1
That will block 192.168.0.1 from visiting your website.
Implied Range 192.168.0.1-40It'll do the same as above but you can enter the details in this format as well.
CIDR Format 192.168.0.1/32/32 is a network mask of 255.255.255.255 so 192.168.0.1/32 = IP address of 192.168.0.1. You can use IP Calculator/IP Subnetting to get a better idea of this.
Implies 192.*.*.* 192.It blocks the entire pool of IP addresses in the range of 192.
