How identifying is your VPN exit, really?

Click run. We measure your exit IP against public VPN relay lists, probe WebRTC and DNS for leaks, and hash your browser fingerprint — then score you 0–100. Nothing is stored beyond a salted hash.

  1. IP intelligence…
  2. VPN exit cross-check…
  3. WebRTC STUN probe…
  4. DNS resolver heuristic…
  5. Browser fingerprint…
What do these axes mean?
IP pool
Whether your exit IP is a well-known VPN with many shared users (you blend in) or a rare/unknown exit (you stand out).
ASN entropy
How common your AS number is among recent scans.
WebRTC
STUN candidate gathering exposes IPs other than your exit — that's a leak.
DNS resolver
Heuristic: if the resolver that fetched our probe sits on a different ASN than your exit, your DNS likely is not tunnelled. Not a true wildcard-DNS test.
Fingerprint
Canvas + AudioContext + UA + screen + timezone + font probe → SHA-256, compared against the corpus of past scans.
