Key takeaways
- This tool queries a set of DNSBL (DNS-based blackhole list) zones, also called RBLs (real-time blocklists), for the domain or IP address you enter, and names every list that reports it.
- Listings usually come from spam sent through the address, a compromised server, or a shared IP address damaged by a previous user; each list publishes its own delisting procedure.
- The lookups run from HostTracker's own check network rather than the location fleet, because a blacklist answers the same from anywhere.
- It is free, needs no login and no credit card.
- For continuous checks, see the DNS blacklist monitoring page, where the lists are rechecked every 6 hours.
