WebRTC leak test
WebRTC is a voice/video calling feature built into the browser. In some cases it can reveal your internal IP or even your real IP, even when you are using a VPN. Press the button to test right on your machine — no data is sent to a server.

What is the difference between a public IP and a private IP?
A public IP is the address your ISP assigns to your connection — it is the number shown above, and every website can see it. A private IP (usually starting with 192.168.x.x, 10.x.x.x, or 172.16–31.x.x) only exists inside your home LAN/Wi-Fi, is assigned by the router to each device, and cannot be reached directly from the Internet.
How are IPv4 and IPv6 different?
IPv4 has 4 groups of numbers separated by dots (e.g. 203.0.113.25), about 4.3 billion addresses in total, and it is now exhausted. IPv6 is much longer, written in hexadecimal separated by colons (e.g. 2001:0db8::1), providing a nearly unlimited number of addresses. Many devices today use both in parallel, so the IP you see may be IPv6.
Why does my IP address change?
Most home users are given a dynamic IP: the ISP reassigns the address whenever you restart the modem, lose the connection, or after a set cycle. The IP also changes when you switch from Wi-Fi to 4G/5G, move to a different café, or use a company network. If you need a fixed address (running a server, camera, or private VPN) you must subscribe to a static IP plan with your ISP.
How do VPNs and proxies affect this?
When a VPN is on, all traffic goes through an intermediary server, so websites only see the VPN server's IP instead of your real IP — the number above will change to the country you choose. However, a VPN is not always airtight: WebRTC leaks, DNS leaks, or a VPN dropping suddenly can all expose your original IP. Use the WebRTC test above to verify for yourself.
What Is My IP Address
Wondering what is my IP? This page shows the public IP address every website sees when you visit, with a label telling you whether it is IPv4 or IPv6.
Beyond the number itself, it lists what your browser is quietly revealing: user agent, operating system, screen resolution, timezone, language and CPU cores. It also includes a WebRTC leak test, which can expose your real IP even while a VPN is switched on.
How to check your IP address
- Open the page — your public IP appears immediately in the large panel at the top.
- Check the badges below it for the IP version and, where available, the country.
- Click "Copy" to grab the address, or reload to check again.
- Scroll to the WebRTC leak section and start the test.
- Any address listed there is leaking through WebRTC, even if a VPN is active.
Key features
- Shows your public IP and detects whether it is IPv4 or IPv6.
- Flags addresses that fall inside private or reserved ranges.
- Names the header the address came from, useful behind Cloudflare or a proxy.
- Detects your browser and operating system from the user agent.
- Device details: screen resolution, window size, timezone, CPU cores, cookie status and language.
- A WebRTC leak test that runs entirely on your device and separates local addresses from exposed public ones.
FAQ
What is the difference between a public and a private IP? The public IP is assigned by your internet provider and is visible to every website. A private IP is handed out by your router to devices on your home network, usually starting with 192.168, 10. or 172.16 to 172.31, and cannot be reached from the internet.
Why does my IP address keep changing? Most home connections use a dynamic IP, so the provider reassigns it after a modem restart, a dropped connection or a set lease period. It also changes when you move between Wi-Fi, mobile data and other networks.
Does a VPN really hide my IP? Mostly. Websites see the VPN server address instead of yours, but WebRTC leaks, DNS leaks or a sudden VPN drop can still expose the original IP.
What is a WebRTC leak? WebRTC powers in-browser voice and video calls. To connect, it gathers your device network addresses, and in some setups a website can read them — revealing your local or real IP even behind a VPN.
