DroneBL lookup and removal

Open proxies, botnet drones and abusive hosts, mostly reported by IRC networks. Few mail filters use it, but a hit points to an infected or open host. Check your IP below, then follow the removal steps if it is listed.

Checks run by DNS only. Nothing is sent from or to your domain.

How to get removed from DroneBL

DroneBL has a self service removal form. Fix the cause first, then submit the listed IP or domain.

  1. 1 Look up the IP address on the operator's site and read the listing reason and return code.
  2. 2 Find the cause on the sending host: a compromised mailbox or script, an open relay, a missing or generic PTR record, a sudden volume spike or a stale list hitting spam traps.
  3. 3 Fix the cause before asking for removal. A list that relists you quickly usually takes longer to remove you the second time.
  4. 4 Open the removal page (https://dronebl.org/lookup), enter the listed IP address and follow the confirmation steps (often an email link).
  5. 5 Re-check the IP address here after the next zone update to confirm the listing is gone. Monitoring alerts you if it comes back.
