IP Deny Manager allows you to block access to your web site from a specific IP address or IP address range.
On the cPanel main page, scroll down to the Security section. Click the IP Deny Manager icon. This takes you to the IP Deny Manager screen. In the section called 'Add an IP to Deny' Enter the IP address you wish to block in the first box. Click the Add button, and it will take you to the verification page. You have successfully blocked anyone from that IP from accessing your web site. Click the Go Back link.
Next on the page you will see a list of Current IP Addresses being blocked. At the end of each IP is a button to click if you wish to remove them from the blocked list. After clicking remove, click Yes to confirm, and the IP will no longer be blocked from your web site.
