Multi RBL Checker
Check any IP address or hostname against 200+ public DNS blacklists simultaneously. Results stream in real-time as each list is queried, with FCrDNS verification included.
How Multi RBL Checking Works
A Multi RBL check queries your IP or hostname against a comprehensive catalog of DNS-based blacklists (DNSBLs), whitelists, and informational lists maintained by security organisations worldwide.
The check also performs Forward-Confirmed reverse DNS (FCrDNS) verification to validate that your PTR records correctly resolve back to the original IP address.
Blacklists
Lists that flag IPs for spam, malware, or abuse
Whitelists
Lists of known-good senders and trusted sources
Informational
Neutral lists providing metadata (e.g., dynamic IP ranges)
