IP Blacklist Check

Real DNS lookups against major spam databases (DNSBL). Works for IPv4 addresses.

Showing your current address 216.73.216.180.

What if I'm listed?

  1. Confirm you're not sending spam, running an open relay or compromised service.
  2. Contact the listing database directly — each has a delisting page.
  3. Residential ISPs share ranges; sometimes a router restart assigns a clean IP.
How does this check work?

Spam databases publish DNS zones. Reversed IPs are looked up inside each zone; an answer (127.0.0.x) means the address is listed, while no answer means it is clean.

Am I permanently blocked?

No. Deletion is automatic in most databases after the cause is fixed and the listing expires. IPv4 addresses are routinely shared, so a clean range matters.
