VPN & Proxy Check
Check whether an IP address is associated with a VPN, proxy, Tor exit node, hosting network or anonymous connection.
What is a VPN and proxy detection check?
A VPN or proxy check looks for network signals suggesting that an IP address is associated with anonymization, hosting, proxy infrastructure, Tor or a commercial VPN service.
Detection is based on external data and network characteristics rather than direct access to the user’s device. Because providers change infrastructure frequently, results should be treated as indicators rather than absolute proof.
How to use VPN & Proxy Check
- Enter the IPv4 or IPv6 address you want to inspect.
- Run the detection check.
- Review VPN, proxy, Tor, hosting, anonymity and confidence signals returned by the provider.
Understanding VPN and proxy results
A positive VPN or proxy signal means the data provider associates the address with that type of infrastructure. Hosting and anonymous-network signals are related but separate and should not be interpreted as automatically malicious.
False positives and stale classifications are possible. Shared cloud networks, corporate gateways and mobile infrastructure can sometimes resemble anonymization services from the perspective of an external detection system.
Common uses for VPN and proxy detection
- Investigate whether traffic appears to come through an anonymizing service.
- Add context to fraud, login or abuse investigations.
- Compare an IP reputation signal with ASN and geolocation data.
- Check whether a server address belongs to known hosting infrastructure.
- Review VPN detection before applying access or risk policies.
