This is the Blacklist Lookup, the all-in-one tool to use for checking if your site’s IP address is listed on an anti-spam database. You can find out and check that your site’s IP address is not banned on specific databases or if it is flagged by these databases. If spam hits your website, search engines also blacklist your site's IP address for security purposes. Sometimes, webmasters might not be aware that search engines have banned their website's IP.
