Check if your IP address belongs to a VPN, proxy, or datacenter. Free VPN detection tool — instant results.
Detection is based on ASN type. Datacenter/VPN provider ASNs are flagged. This is an estimate — not all VPNs are detected.
VPN detection compares your IP address's Autonomous System Number (ASN) against known lists of datacenter and VPN provider IP ranges. If your IP belongs to DigitalOcean, AWS, NordVPN, Mullvad, ExpressVPN, or similar providers, it's likely a VPN.
Residential VPNs (which route through real home connections) are much harder to detect and may not be flagged by this tool.
VPNs encrypt your internet traffic, hide your real IP address, bypass geographic restrictions, and prevent your ISP from seeing your browsing activity. Popular use cases include privacy protection, accessing streaming content from other countries, and securing connections on public Wi-Fi.
We compare your IP Autonomous System Number (ASN) against known datacenter and VPN provider IP ranges. If your IP belongs to providers like NordVPN, ExpressVPN, DigitalOcean, or AWS it is flagged as likely a VPN. Residential VPNs routing through real home connections are much harder to detect.
Streaming services block VPNs to enforce geographic licensing. Banks flag VPN IPs for fraud prevention. Gaming platforms block them to enforce regional pricing. Detection uses ASN comparison matching your IP against known datacenter and VPN provider ranges.
