The IP Address Deny Manager tool in cPanel allows you to prevent an IP address, domain name, or block of IP addresses from accessing your web site. If someone is using a lot of your bandwidth, posting malicious content, or should not be allowed to access your site for another reason, you can prevent them from doing so in the IP Deny Manager.
Deny access to a domain or IP
To access the IP Address Deny Manager, click on its tool icon in the Security section of your cPanel interface.
Once the page loads add the desired IP, IP range or hostname in the IP Address or Domain field and click the Add button.
You will be redirected to a confirmation page showing that the changes have been applied.
Allow access to a denied IP address
If you no longer wish to deny access from a specific IP address, you can use the IP Address Deny Manager to allow access from that IP address. To do that, click the Delete button next to the entry for the IP, IP range or hostname that you no longer want to block.
