VPN Connection Checker
See exactly what the internet sees about your connection — public IP, geolocation, ISP, and whether your IP looks like a VPN, proxy, or datacenter address. Includes a WebRTC leak test that runs in your browser.

WebRTC Leak Test
Public IPs leaked via WebRTC
✓ None — your VPN (if any) is correctly tunneling WebRTC.
What we send where: Your public IP (which every site sees automatically) is forwarded to ip-api.com for geolocation and datacenter classification. The WebRTC leak test runs entirely in your browser and connects to Google's public STUN server (stun.l.google.com) — those local IPs never reach our backend.
What we store: Nothing. No logs, no database writes, no cookies. Each check is one-shot.
How VPN detection works:We match your IP against datacenter ranges and known VPN provider org names. A “likely VPN” verdict means your IP signals match a VPN/proxy. False negatives are possible — small VPNs can blend in with regular ISPs.
