Use our free IP blacklist checker to instantly find out if your IP address is listed on major spam or security blacklists. Quickly check your IP against trusted DNS blocklists to fix issues with email delivery, server access, or site availability.
What is an IP blacklist?
An IP blacklist is a database of IP addresses known to send spam, distribute malware, or engage in other abusive behavior online. These blacklists are used by email providers, network administrators, and firewalls to block unwanted traffic. If your IP is listed, your emails may be rejected or marked as spam, and your server might be blocked from connecting to other systems. Using an IP black list checker helps you detect this early and take action.
How do I check if my IP is blacklisted?
You can easily check black list IP status using the Pixelscan IP black list checker. It will scan your IP across dozens of DNS-based blacklists (DNSBLs). Within seconds, you'll see whether your IP is listed and where.
Why is my IP address on a blacklist?
- Your network may have been infected with malware or used to send spam.
- You're using a shared IP that was previously abused by someone else.
- You sent a large number of emails that were marked as spam.
- You use weak security settings that allow others to misuse your IP.
How do I get my IP removed from a blacklist?
- Use our black list IP checker to identify where your IP is listed
- Visit the website of each blacklist that flagged your IP.
- Follow their instructions—some offer automatic removal if the issue is resolved; others require a manual request.
- Ensure your system is clean and secured to avoid repeat listings (e.g., run malware scans, update server configs).
- Monitor your IP with a regular IP black list check.
