Acutis Find your real IP — even behind a VPN or proxy
Most "what's my IP" sites show your VPN, proxy or corporate-filter exit. This one looks for the IP they can't hide — your true address.
A VPN, proxy or corporate filter is masking you from websites — but this is your true address, leaked through WebRTC. If you thought you were hidden, you're not.

Why this finds what other sites can't
A normal "what's my IP" page reads the address your web traffic exits from. Run it through a VPN, a proxy, or a corporate gateway like Zscaler, and that's all it sees — the exit, not you. But your browser's WebRTC uses a separate path (STUN/UDP) that often slips past those tunnels, exposing your real public IP anyway. That's the leak this tool surfaces:
- WebRTC leak — your true public/local IP exposed through real-time-communication, even with a VPN, proxy, or SWG in front.
- IPv6 leak — many VPNs only tunnel IPv4; your real IPv6 (shown above) walks right out.
- DNS leak — lookups that slip outside the tunnel and expose your ISP. (Deeper test coming.)
Not behind anything? Then the IP up top is simply your home connection — nothing's leaking, you're just you.
FAQ
Can a website see my real IP if I use a VPN?
Often, yes. Your browser's WebRTC can leak your true public (and local) IP through a separate path that bypasses the VPN tunnel — which is exactly what this tool surfaces. Many VPNs also don't tunnel IPv6, so your real IPv6 can leak too.
How do I find my real IP behind a VPN or proxy?
Open this page with your VPN or proxy turned on. The "IP that websites see" is the VPN exit; if a WebRTC or IPv6 leak is detected, your real address appears at the top. It runs in your browser and nothing is stored.
What is a WebRTC leak?
WebRTC is a built-in browser feature for real-time audio/video. It can ask STUN servers for your real IP over UDP, slipping past VPNs and proxies — leaking the address you thought was hidden.
Is this tool free and private?
Yes. It's free, needs no sign-up, runs entirely in your browser, and nothing touches Acutis servers.
Your network hides things. Acutis doesn't.
If a corporate filter can't hide your IP from a web page, imagine what's quietly happening on the network you actually run. Acutis Go runs a 60-second check and tells you plainly whether a problem is the network or your own machine — no guessing, no hiding. Free.
