IP blacklist check
Is your IP on a blocklist, a known proxy or a Tor exit? One risk score from 12 blocklists and our own proxy data.
The check combines two kinds of evidence. Our own data: whether the address is in the public proxy lists right now, whether it has ever been in them (about 2 million addresses since 2022), whether it is a Tor exit node, and whether it belongs to a cloud or datacenter network. Then 12 DNS blocklists (DNSBLs) that mail servers and firewalls use to reject spam, botnets and abuse.
How the score works
- +45 if the address is a public proxy right now; +20 if it was one in the past.
- +35 for a Tor exit node.
- +12 per blocklist that lists it, up to +50.
- +10 for a cloud or datacenter address: not bad in itself, but many sites treat it with suspicion.
0–14 is clean, 15–39 low, 40–69 medium and 70–100 high risk.
Listed? What to do
On a shared or dynamic address (mobile, CGNAT, a VPN) the listing usually belongs to someone else; reconnecting often gives you a new address. If it is your own server, find out why it was listed (an open proxy, malware, a compromised account sending mail), fix that first, and then follow the removal process of each blocklist via its link above. A listing in our proxy data disappears from the current lists within 20 minutes once the proxy is closed.
