About Blacklist Lookup

Comprehensive IP Blacklist Checker

Check if your website or mail server IP address is listed in any spam blacklists (DNSBL - DNS-based Blackhole Lists). Being blacklisted can prevent email delivery and harm your online reputation. This tool checks against 100+ major blacklist databases.

How to Check Blacklists:

1. Enter your domain or IP address
2. Click "Check Blacklist Status"
3. Get results from multiple blacklist databases:
   • Spamhaus
   • SORBS
   • Barracuda
   • SpamCop
   • And 90+ more
4. View which lists (if any) have blacklisted your IP

Why Blacklisting Happens:

• Sending spam emails
• Compromised server
• Malware/virus infection
• Shared hosting with spam neighbors
• Poor email practices

If Blacklisted: Identify the cause, clean your server, improve email practices, and request delisting from each blacklist.
