WebRTC Leak Test: Is Your Real IP Exposed Right Now?
You turned on your VPN. You feel safe. But websites might still know your real IP address — and you have absolutely no idea it’s happening.
This is called a WebRTC leak, and it silently bypasses VPNs, proxies, and privacy tools millions of people rely on every day.
The good news: it takes about 5 seconds to find out if you’re affected.

The test shows you exactly what IP addresses your browser is broadcasting — including any local or real IPs leaking through WebRTC. Take note of what you see. Then keep reading to understand what it means.
What Is WebRTC — And Why Should You Care?
WebRTC (Web Real-Time Communication) is a browser technology built for things like video calls, voice chat, and peer-to-peer file sharing — all without plugins.
It’s built into Chrome, Firefox, Edge, Opera, and Brave by default.
Here’s the problem: to establish direct connections between devices, WebRTC needs to know your real IP address. And it can reveal that address even if you’re connected to a VPN.
Not sometimes. Every time — unless you’ve explicitly blocked it.
How WebRTC Leaks Work
When your browser uses WebRTC, it communicates through something called ICE (Interactive Connectivity Establishment). This protocol gathers all available network interfaces — including your actual local network and real public IP — and shares them to find the best connection path.
Your VPN tunnel routes your regular traffic through a different IP. But WebRTC operates outside of that tunnel in many configurations.
The result: a website running WebRTC can see both your VPN IP and your real IP simultaneously.
This isn’t a bug in your VPN. It’s a browser-level behavior that most VPNs never touch.
What Most People Get Wrong About WebRTC Leaks
Myth 1: “My VPN protects me from WebRTC leaks”
Reality: Most VPNs do not block WebRTC by default. Some claim to, but few do it consistently across all browsers. Unless your VPN explicitly disables WebRTC at the browser level, you’re likely still leaking.
Myth 2: “Incognito mode fixes this”
Reality: Incognito mode doesn’t disable WebRTC. Your browser still has full WebRTC capabilities in private browsing — it just doesn’t save your history.
Myth 3: “I’d notice if my IP was leaking”
Reality: There’s no visual warning. No browser alert. No VPN notification. Leaks happen silently, in the background, every time a page uses WebRTC — which is more common than you think.
Myth 4: “This only matters for extreme privacy cases”
Reality: If you manage multiple accounts, run browser automation, use proxies for business purposes, or simply don’t want your ISP and real location tied to your browsing — WebRTC leaks are a real threat to your setup.
Who Is Actually at Risk?
WebRTC leaks aren’t just a concern for activists or hackers. They affect a wide range of everyday users:
- Multi-account managers — platforms detect IP mismatches and flag accounts
- Affiliate marketers and media buyers — ad platforms correlate IPs across accounts
- Remote workers using proxies to access geo-restricted services
- Automation specialists running browser scripts that need clean fingerprints
- Privacy-conscious users who believe their VPN is doing its job
If you fall into any of these categories, a WebRTC leak could be actively damaging your setup right now.
How to Do a WebRTC Leak Test (Step by Step)
Here’s how to run a proper test WebRTC leak check and actually understand the results:
- Keep your current setup active — VPN on, proxy connected, or whatever you normally use
- Go to WebRTC checker
- Let the scan run — it takes a few seconds
- Look at the results:
- If you see only your VPN/proxy IP → you’re clean
- If you see a second IP that doesn’t match your VPN → that’s your real IP leaking
- If you see local IPs like 192.168.x.x → less critical, but still a fingerprinting signal
- Repeat the test with your VPN off to compare baseline results
The difference between those two scans tells you exactly how much your VPN is actually protecting your WebRTC traffic.
What Pixelscan Shows You That Other Tests Miss
Most basic WebRTC tests show you a single IP. That’s a start — but not the full picture.
Pixelscan’s WebRTC leak test goes deeper:
- Shows all IP candidates gathered by WebRTC (not just the top one)
- Flags inconsistencies between your WebRTC IP, HTTP IP, and DNS resolver
- Combines results with your full browser fingerprint to show the complete picture of what tracking systems can see
- Runs as part of an all-in-one privacy scan — so you check WebRTC, DNS, VPN, and fingerprint in a single session
For anyone managing multiple profiles or running proxies at scale, this level of detail matters. A single IP mismatch between layers can be enough to trigger account flags on major platforms.
How to Fix a WebRTC Leak
Depending on your browser and setup, here are your options:
Option 1: Disable WebRTC in Firefox
Firefox allows you to disable WebRTC entirely:
- Type about:config in the address bar
- Search for media.peerconnection.enabled
- Set it to false
This completely blocks WebRTC — no leaks possible, but also no WebRTC-based apps.
Option 2: Use a Browser Extension (Chrome/Edge)
Extensions like WebRTC Control or uBlock Origin (with the right settings) can block WebRTC on Chromium browsers. Results vary — always test afterward.
Option 3: Use an Antidetect Browser
If you’re managing multiple accounts or need consistent, leak-free profiles at scale, a dedicated antidetect browser handles WebRTC at a deeper level.
Multilogin lets you configure WebRTC behavior per profile — set it to disabled, use real-looking values, or spoof it entirely. Each browser profile is isolated, and WebRTC can’t leak across sessions or back to your real IP.
For proxy-heavy workflows, NodeMaven pairs well here — clean residential IPs combined with properly configured WebRTC settings close the most common detection gaps.
Option 4: Verify After Every Change
This is the step most people skip. After you apply a fix, run the test again. Assumptions are how leaks survive. A 5-second check at Pixelscan confirms whether your fix actually worked.
The Bigger Picture: WebRTC Is Just One Signal
Here’s something worth understanding: even if you fix your WebRTC leak, you’re not fully invisible.
Tracking systems use dozens of signals simultaneously — your browser’s canvas fingerprint, fonts, screen resolution, timezone, language settings, and more. WebRTC is one piece of a larger detection puzzle.
That’s why testing WebRTC in isolation only tells part of the story.
If you want to see the full picture of what tracking systems actually see when you visit a site, run a complete browser scan — not just a WebRTC check.
FAQ
A WebRTC leak test checks whether your browser is exposing your real IP address through the WebRTC protocol — even when you’re connected to a VPN or proxy. It compares the IPs broadcast by WebRTC against your expected (masked) IP to detect any mismatch.
Visit pixelscan.net/webrtc-check. The test runs automatically in your browser with no registration or install required. Results appear within a few seconds.
Not automatically. Most VPNs route your regular internet traffic but don’t interfere with WebRTC’s IP gathering process. Unless your VPN specifically disables WebRTC or you do it manually in your browser, leaks are likely.
Yes. Platforms that track IP addresses across sessions — including social networks, ad platforms, and marketplaces — can use WebRTC-leaked IPs to link accounts or flag suspicious activity. This is a real concern for multi-account managers.
No. Incognito (or private) mode doesn’t disable WebRTC. Your browser still has full WebRTC capability in private windows, and leaks occur the same way they do in regular mode.
Chrome doesn’t have a built-in toggle. Your options are: use an extension (WebRTC Control), switch to Firefox and disable it via about:config, or use an antidetect browser like Multilogin that manages WebRTC per profile.
Seeing private IPs like 192.168.x.x or 10.x.x.x means WebRTC is exposing your internal network addresses. This is less critical than a public IP leak, but it’s a fingerprinting signal that can help identify a device or network setup.
No. DNS leaks, IPv6 leaks, and HTTP headers can also expose your real IP. Running a full multi-check scan on Pixelscan covers all of these simultaneously.
Conclusion
Most people discover WebRTC leaks the hard way: after an account ban, a flagged profile, or a privacy incident they can’t explain.
The frustrating part is that it’s entirely avoidable. You don’t need a technical background or an expensive setup. You just need to actually check — and then fix what you find.
A VPN is a good start, but it was never designed to handle everything the browser exposes on its own. WebRTC is a perfect example of that gap. It operates at the browser level, not the network level, which means it quietly sidesteps most conventional privacy tools unless you take deliberate steps to address it.
If you’re managing accounts, running proxies, or simply care about what your browser says about you — treat this as a baseline check, not a one-time task. Browser environments change with updates. Extensions conflict. Configs break. A quick re-test every few weeks costs nothing and tells you everything.
