About Blacklist Lookup

The Blacklist Lookup Tool is a Free SEO Tool that allows checking if your IPs have been blacklisted by querying over 100 known public DNS blacklists. Enter the IP address, a hostname, or domain name to look up and you can use our Multi-RBL to check whether your IP address is listed within the main RBLs.
