WebRTC Leak Check

Testing WebRTC peer connection
What is a WebRTC leak? WebRTC is a browser API for peer-to-peer connections (video calls, etc.). It can reveal your local network IP (e.g., 192.168.x.x) even when you are using a VPN. A local IP leak is usually harmless — your public IP is still hidden. Some advanced VPNs block this entirely.

Is my VPN working?

If your public IP above matches your VPN server's country, your VPN is working. The "VPN or proxy" badge in the hero card confirms your connection appears as a VPN to websites. The WebRTC check above verifies whether your real local IP is leaking through the browser's peer connection API.

What Can Websites See About You?

Every time your browser visits a website, it automatically reveals more than most people realize — without any login or tracking cookie required.

From your IP address alone:

  • Approximate location — typically accurate to your city (rarely to your street).
  • Internet Service Provider (ISP) — the company providing your internet service.
  • Whether you appear to use a VPN, proxy, or Tor exit node — data centers have known IP ranges.
  • IPv4 or IPv6 — which version of the protocol your connection uses.

From your browser's JavaScript (no cookies needed):

  • User agent — your browser name, version, OS, and device type.
  • Screen resolution & color depth — used in fingerprinting.
  • Timezone — your local time zone, regardless of what country your IP suggests.
  • Language settings — the languages you've set in your browser preferences.
  • Installed fonts, canvas rendering, WebGL — collectively used to build a "fingerprint" unique to your browser, even without cookies.

Most of this information is transmitted automatically by your browser as part of how the web works. A privacy-focused browser like Firefox with uBlock Origin and a good VPN significantly limits what sites can reliably identify.

IPv4 vs. IPv6 — What's the Difference?

IPv4 uses 32-bit addresses written as four numbers (e.g., 203.0.113.42). With only ~4.3 billion possible combinations, the world effectively ran out of IPv4 addresses around 2011. ISPs now use techniques like CGNAT (Carrier-Grade NAT) to share addresses across many customers, meaning your "public" IPv4 may be shared with neighbors.

IPv6 uses 128-bit addresses written in hexadecimal groups (e.g., 2001:db8:85a3::8a2e:370:7334). With 3.4 × 10³⁸ possible addresses, IPv6 will not run out — every device can have a globally unique address. IPv6 adoption has passed 40% globally but rollout is still uneven across ISPs and countries.

Practical difference for you: If your browser shows both an IPv4 and an IPv6 address, your ISP supports dual-stack connectivity. Many websites now prefer IPv6 when available. VPN software typically routes both; some older VPNs only route IPv4 and can leave your IPv6 address exposed.

When Should You Use a VPN?

A VPN (Virtual Private Network) replaces your public IP address with one from the VPN server and encrypts traffic between your device and the VPN. Here is an honest guide to when it helps — and when it doesn't.

Situations where a VPN genuinely helps:

  • Public Wi-Fi (cafés, airports, hotels) — encrypts traffic from local network eavesdroppers.
  • Hiding activity from your ISP — prevents ISP logging or throttling of specific services.
  • Accessing geo-restricted content — streaming services, news sites, or services blocked in your region.
  • Confirming geo-location (this tool) — lets you verify the VPN server's IP is showing correctly.

What a VPN does NOT do:

  • Make you anonymous — the VPN provider can see your traffic; they have your payment info.
  • Hide your identity from websites where you are logged in.
  • Protect you from malware, phishing, or browser fingerprinting.

Bottom line: Use a reputable VPN with a no-logs policy for public Wi-Fi and ISP privacy. Don't rely on it for full anonymity.

Frequently Asked Questions

What is an IP address?
An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a network. It tells other computers how to route data back to you — similar to a postal address for internet traffic. You have a public IP (visible to websites you visit, assigned by your ISP) and one or more private IPs (used only inside your local network, e.g., 192.168.1.5).
What can a website see from my IP address?
A website can see your public IP, which reveals your approximate city and country, your Internet Service Provider (ISP), and whether you appear to be using a VPN or data center. It cannot see your exact street address, your name, or your browsing history from IP alone.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses (like 203.0.113.42) and supports about 4.3 billion unique addresses. IPv6 uses 128-bit addresses (like 2001:db8::1) and supports a virtually unlimited number, solving IPv4 exhaustion. Many devices now have both simultaneously via "dual-stack" connectivity.
What is a WebRTC leak?
WebRTC is a browser feature for real-time communication (video calls, file sharing). It can reveal your local network IP address — even when using a VPN — because it uses a different code path than normal browser traffic. Some VPNs block this; others do not. A local IP leak (like 192.168.x.x) typically doesn't expose your public identity, but is still worth knowing about.
Does checking my IP here reveal my info to anyone?
No. All browser-signal detection runs entirely in your browser via JavaScript. The only network request this page makes is to ipify.org (and ipapi.co for enriched location) to retrieve your public IP. Both are widely trusted, privacy-focused services. We do not store, log, or transmit any of your information to our own servers. This site is 100% static with no backend.
Should I use a VPN?
A VPN can mask your public IP and ISP from the websites you visit, which is useful on untrusted public Wi-Fi and for bypassing geo-restrictions. It doesn't make you fully anonymous — the VPN provider can see your traffic. Use one from a reputable provider with a verified no-logs policy if privacy from your ISP or public Wi-Fi security matters to you.
