VPN Detector — Check Any IP for VPN, Proxy & Tor
Paste any IPv4 or IPv6 address to find out whether it is hiding behind a VPN, a proxy (datacenter, residential, or mobile), a Tor exit node, or a private relay. The detector returns a clear yes/no verdict for each type, names the provider where it is known, and gives a confidence score so you can see how certain the result is — telling an ordinary visitor from masked traffic in seconds. It runs free in your browser, with no account required.

What the VPN Detector checks
Enter an IP address and the tool tells you whether the connection is anonymized and what kind. The result is built around one question — is this IP masked, and how?
- VPN, proxy, Tor, relay, and datacenter verdicts: A clear yes/no for each way traffic hides its origin: VPN, proxy (datacenter, residential, or mobile — residential proxies look like ordinary home connections), Tor exit node, private relay, and datacenter/hosting ranges, which are rarely real end users. A single "anonymous" flag tells you at a glance whether the IP is masked by any of these.
- Provider names: Where the anonymizer is known, the result names the VPN, proxy, or relay provider — so you can recognize repeat sources and tell a commercial VPN from a one-off proxy.
- Confidence scores: A 0–100 confidence score for the VPN and proxy verdicts, so you can see how certain the detection is rather than just whether a flag is set. The result also reports when the IP was last seen acting as a VPN or proxy.
This tool reports anonymizer detection only. It does not return the IP's location, ISP, ASN, or an abuse/fraud reputation score. For location and network details use the IP to ISP Lookup or IP to ASN Lookup tools; for fraud scoring and IP reputation use the IP Threat Intelligence API.
How to use the VPN Detector
- Type or paste an IPv4 or IPv6 address into the input field.
- Click Detect (you may be asked to complete a quick CAPTCHA on first use).
- Review the result: VPN / proxy / residential proxy / Tor / relay / datacenter verdicts, the provider name where known, and the confidence score.
- Switch to the JSON view to see the full raw result.
When this tool helps
- Check whether an IP is anonymized. Run a single address from a log, an order, or a sign-up to see whether it's a VPN, proxy, Tor, or datacenter connection rather than an ordinary visitor.
- Identify the anonymizer type and provider. Tell a commercial VPN from a residential proxy or a Tor exit node before you decide how to treat the traffic.
- Check whether your own VPN is working. Run your current IP through the detector to confirm it's flagged as a VPN rather than showing up as your real, unmasked connection.
FAQs
Paste the IPv4 or IPv6 address into the box and click Detect. The tool returns a clear VPN verdict for that address, along with proxy, Tor, relay, and datacenter checks.
The result labels the anonymizer type. A VPN routes all traffic through an encrypted tunnel; a proxy forwards specific requests and can be datacenter, residential, or mobile. The tool reports each separately so you can tell them apart at a glance.
Yes. If the IP is a known Tor exit node at the time of the check, it is flagged. Tor traffic signals a strong intent to stay anonymous.
Yes. Residential proxies route through real home connections and are harder to spot; datacenter proxies come from hosting ranges. The tool flags both, along with the provider name where it is known.
Detection is highly accurate for VPN and proxy identification, drawn from continuously updated data on anonymizer infrastructure, and each VPN and proxy verdict comes with a 0–100 confidence score so you can see how certain the result is.
Yes. The detector accepts both IPv4 and IPv6 addresses.
Connect to your VPN, then run your current IP through the detector. If it's working, the result should flag the IP as a VPN — and often name the VPN provider. If it comes back as not a VPN and not anonymous, your traffic may not be routed through the VPN.
It means a site has identified your connection as coming through a proxy, VPN, or other anonymizer rather than a normal connection. Paste the IP into the detector to see which type was flagged.
The tool is free to use in your browser with no sign-up. An account is only needed if you later want to automate checks through the API.
A VPN (virtual private network) routes your internet traffic through a remote server and encrypts the connection between your device and the internet. It hides your real IP address and makes it harder for third parties to see your location or track your activity.
No — a VPN is a legitimate privacy and security tool. Some sites still treat VPN traffic with extra caution because it hides a visitor's real location, which is why anonymized connections are sometimes asked to verify before sensitive actions.
