URL BlackList Checker

Enter a domain name or URL to perform blacklist check.

This URL Blacklist Checker tool helps you verify whether a domain name is flagged on various URI Blacklists (URIBLs). URIBLs are lists that track domain names found in spam emails, phishing attempts, or associated with malicious content. You can input either a domain name (e.g., example.com) or a full URL (e.g., https://example.com/page), and the tool will query multiple URIBL services to determine whether the domain is blacklisted.

The results are presented in a table with the following details:

• URI BL: The name of the blacklist.
• Status: The result for each URIBL, which will either be "Listed" (domain is found in the BL), "Not Listed" (domain is not found), or "Error" (the lookup failed due to connectivity or DNS server issues).
• Info: The status code for the listed domain, typically an address from the loopback range (127.0.0.0/8). When available, additional data about why the domain was blacklisted is provided.

Note that status code values and their meanings vary significantly between URIBLs. Many blacklists may use different values to provide reason for why a domain is blacklisted. For example, to categorize the type of malicious activity associated with the domain, such as phishing or malware distribution. It is recommended to visit the URIBL's web site to obtain the detailed status code descriptions:

• junkemailfilter.com
• spameatingmonkey.net
• spamhaus.org
• surbl.org
• uribl.com

For IP-based lookup use our RBL Record Checker.

URI Blacklists (URIBLs) are used to track domain names that appear in spam emails or are linked to malicious activities such as phishing, malware distribution, or fraud. Unlike traditional IP blacklists, which track IP addresses, URIBLs focus specifically on domains that may be part of spam campaigns or harmful web activity.

URIBLs are invaluable in protecting users from visiting malicious websites by flagging potentially harmful domains within emails or online messages. They help with blocking phishing attempts and preventing access to malicious web content.

Performing a URIBL lookup can help you assess the reputation of a domain. If your domain is flagged, understanding the reasons behind the listing allows you to take corrective action, such as resolving security vulnerabilities or clearing your domain from malicious associations, thus improving your site's web reputation and security.
