Stop a specific IP address (for example, an attacker) from reaching your site.

1. Log in to cPanel.
2. Go to Security > IP Blocker.
3. Enter the IP address or range you want to block.
4. Click Add.

That IP can no longer access your website.

Tip: You can find offending IPs in your raw access logs or a security plugin's logs. Be careful not to block your own IP or legitimate visitors.
