About Blacklist Lookup

The Blacklist Lookup tool lets you check whether your domain or IP address is listed on any known DNS-based blacklists (DNSBLs). These blacklists are used by spam filters and security systems to block malicious or suspicious traffic. This tool is essential for email deliverability, website reputation, and network security.

Key Features:

  • Checks domain/IP against major blacklists

  • Covers spam, phishing, and malware blacklists

  • Fast and accurate scanning

  • Helps maintain email and server reputation

  • No login or software required

Use this tool to ensure your website or mail server isn't blacklisted and to take corrective actions if needed.
