When a particular address is causing trouble — hammering your login, scraping your content, or generating spam — the IP Blocker lets you shut it out at the server level, before it ever reaches your website. Here’s how to use it well.
What the IP Blocker does
The IP Blocker adds rules that deny access to your site from specific addresses or ranges. Because it works at the server level, a blocked address can’t load any part of your site — it’s turned away at the door, which is more effective than blocking within your website’s own code.
Blocking an address
- In cPanel, open IP Blocker under the Security section.
- Enter the IP address you want to block in the field.
- Click Add.
That address is now denied access. You can block a single IP, a range, or an entire subnet if you’re dealing with a group of related addresses.
Finding the address to block
To know which address is causing trouble, check your access logs (under Metrics). A brute-force attack shows up as many repeated requests to wp-login.php from one address; a scraper shows as rapid-fire requests across your pages. Note the offending IP and block it.
Use it thoughtfully
A word of caution: blocking too broadly can shut out legitimate visitors, since many people share addresses through their internet provider or mobile network. Block specific troublemakers, not entire countries or wide ranges, unless you’re certain. And remember attackers often rotate addresses, so blocking one is a temporary measure against a determined one.
Blocking your own access by mistake
Take care not to block the range your own connection uses — if you do, you’ll lock yourself out of your site. If that happens, you can still reach cPanel to remove the block, or contact us to clear it.
The bigger picture: server-level protection
For serious or persistent attacks, manual IP blocking is like bailing water with a bucket. Our servers run CSF/LFD, a firewall that automatically detects and blocks addresses showing attack patterns — repeated failed logins, port scans, flooding — without you lifting a finger. This catches far more than manual blocking ever could.
When to escalate to us
If you’re facing a sustained attack, or the same trouble keeps coming from ever-changing addresses, don’t try to win the whack-a-mole alone. Open a ticket and we can apply broader server-side protections, tune the firewall, and put proper defences in place. The IP Blocker is great for one-off nuisances; a real attack is our job.
