Blacklist Check

Resolve your domain to its IP and run authoritative DNSBL checks across the major spam blacklists.

Public DNS-over-HTTPS resolvers are blocked by major DNSBLs (Spamhaus, Barracuda, etc) to prevent abuse — so we can't query them directly from the browser. Instead, we resolve your domain to its IP and link out to the trusted authoritative checkers below for an accurate, real-time result.
