IP Blacklist Checker

See the individual result for an IP address against each specific DNS-based block list checked.

About this tool

This shows the raw, individual result from each specific block list checked — for a single overall clean/listed verdict instead, see the IP Reputation Checker. The list is deliberately small and deliberately excludes any DNSBL whose usage policy restricts high-volume public web-tool queries — this checks a modest, commonly-referenced set, not every blocklist that exists.

If your IP is listed

Each blocklist operator publishes its own delisting process, usually a self-service removal form on their own site once the underlying issue (an open relay, compromised device, spam campaign, etc.) has been resolved. This tool can tell you that you're listed; removal always happens directly with the list operator, not here.
