VPN Test

This page runs an honest, heuristic VPN check: it compares your device's timezone with the timezone of your IP address and looks at who operates your network. It reports signals — it cannot prove or disprove that you are using a VPN.

How this VPN check works

  • Timezone comparison: your operating system knows your local timezone; your IP address maps to a timezone too. When they disagree, your traffic may be exiting in a different region than where you are sitting — a common VPN sign. It also happens when you simply travel, so it is a hint, not proof.
  • Network organization: home connections belong to consumer ISPs, while most VPN exits run in datacenters. We query the public ipwho.is database for the organization and ASN behind your IP and flag names typical of hosting or VPN providers.

What this test cannot do

No website can definitively detect a VPN. A quality VPN exit in your own city on an unremarkable network will pass every heuristic; conversely, a mislabeled ISP or a trip abroad can trigger false signals. Treat the verdict as a starting point, not a fact.

Complementary checks

If you use a VPN, also run the WebRTC leak test (WebRTC can bypass VPN tunnels) and the IPv6 test (many VPNs tunnel only IPv4, letting IPv6 traffic escape). To verify your exit location, use the IP lookup, and see how to hide your IP for how VPNs compare with proxies and Tor.
