Enter any public IP address and we'll tell you whether it belongs to a VPN provider, an open proxy or the Tor network — using the same detection data our API customers rely on.
We combine curated VPN provider ranges, hourly Tor exit node lists, community proxy feeds and our own network probing from 60+ nodes. Every IP is scored 0–100; anything flagged here was seen in at least one authoritative source, most within the last 24 hours.
Fraudulent signups, promo abuse, fake reviews and card testing almost always arrive from anonymized IPs. Checking the connection type before you trust a request is one of the cheapest fraud signals available — and for a single IP you can do it right here, free.
