Am I Using Tor?
Check whether your current IP address matches a known Tor exit node, using the Tor Project's own published list.
Checking your IP against the Tor Project's exit-node list…
This only checks your IP against the Tor Project's own published list of exit-node addresses (refreshed at least daily) — it isn't a live/real-time probe. A brand-new exit node that hasn't propagated to that list yet can produce a false negative ("No" shown for someone actually using Tor), and the check says nothing about VPNs, proxies, or other anonymization tools. Your IP address is sent to our server to run this check — it isn't stored, but this isn't a 100% client-side lookup (see the privacy note on this page).

What is Am I Using Tor??
Tor (The Onion Router) is a free network that routes your traffic through several relays before it reaches its destination, so the website you're visiting sees the IP address of the last relay in that chain — the "exit node" — instead of your real IP. This tool checks whether the IP address your connection is currently using appears on the Tor Project's own published list of exit-node addresses. If it does, you (or whoever shares that exit node) are very likely browsing through Tor. This is a list-based check, not a live network probe: the Tor Project publishes and refreshes its exit-node list at least daily, and this tool fetches and checks against that same list (cached for up to a day at a time). A brand-new exit node that hasn't propagated to the list yet, or a stale fetch of the list, can produce a false negative — this tool saying "No" even though you're actually using Tor. It can't detect VPNs, residential proxies, or other anonymization methods that don't route through the public Tor network.
What an Exit Node Is
A Tor circuit typically passes through three relays: an entry (guard) node, a middle relay, and an exit node. Only the exit node's IP address is ever visible to the website you're connecting to — the entry and middle relays stay hidden from it. Because many Tor users can share the same exit node at different times, a matching IP means that address is a known Tor exit, not that any specific person is using it right now.
Why This Isn't a Security Scanner
This tool is informational, not a verdict on trustworthiness. Being flagged as a Tor exit node doesn't mean the connection is malicious — people use Tor for legitimate privacy reasons (journalists, researchers, people on restrictive or monitored networks, or anyone who simply doesn't want their browsing linked to their IP). Equally, not being flagged doesn't guarantee a connection is Tor-free, for the staleness reasons above.
