WebRTC Leak vs DNS Leak: What’s the Difference & How to Fix?

Hidemyacc Global · Apr 21, 2026

If you are running multiple accounts, a 'green' status on an IP checking site isn't enough. You need to understand what is leaking and why.

1. What is WebRTC Leak?

WebRTC is a browser protocol for real-time communication (voice/video).

Impact: Websites see two different IPs—your Proxy IP and your Real IP.
The Giveaway: It reveals you are masking your identity. Instant flag for platforms like eBay, Etsy, or Facebook.

2. What is DNS Leak?

What it is: DNS (Domain Name System) translates a URL (https://www.google.com/search?q=google.com) into an IP address.The Leak: By default, your computer asks your ISP’s DNS servers for this translation. When you use a proxy/VPN, your traffic might go through the proxy, but the DNS request still goes to your Local ISP.

Impact: The website might see your Proxy IP (e.g., US), but the DNS requests are coming from your home country (e.g., Vietnam).
The Giveaway: It reveals your true geographic location.

3. WebRTC Leak vs DNS Leak: Key differences

Feature	WebRTC Leak	DNS Leak
Origin	Browser-level (API/Protocol)	System-level (Network settings)
Protocol	Mostly UDP	DNS queries (Port 53)
Information	Reveals Local & Public IP	Reveals ISP & Country
Detection	JavaScript can trigger this	Checked by monitoring DNS requests

4. How to Fix them?

4.1. For WebRTC Leaks

To fix a WebRTC leak, you can refer to the following three methods:

Using antidetect browser: Modern anti-detect browsers all feature capabilities that allow you to spoof your WebRTC IP to perfectly match your proxy IP.
Disable WebRTC: (Not recommended for high-stealth) Turning it off completely in Chrome/Firefox flags makes you look like a bot.
Use UDP proxies: Most cheap SOCKS5 proxies don't support UDP, which is why WebRTC leaks occur. Use high-quality providers that support full UDP tunneling.

4.2. For DNS Leaks

To fix a DNS leak, you can refer to the following three methods:

Hardcode DNS: Change your network adapter settings to use Public DNS (Google 8.8.8.8 or Cloudflare 1.1.1.1) instead of your ISP's.
Force DNS through Proxy: Ensure your browser/tool is configured to resolve DNS remotely (on the proxy side) rather than locally.
VPN Killswitch: If using a VPN, ensure "DNS Leak Protection" is toggled on.

In conclusion:

WebRTC Leaks reveal WHO you are (your exact IP).
DNS Leaks reveal WHERE you are (your ISP/Location).

I hope this insight helps. DNS leaks and WebRTC leaks can seriously impact your accounts, especially if you’re managing multiple accounts on the same device. Taking the time to understand how they work and how to fix them will give you a much stronger setup and reduce the risk of detection.

biggest mistake is when you treat leaks as only an ip problem. the real headache is consistency, if your brower says one region and your dns resolves somewhere else, and the session timing lines up with a fresh cgnat hop, that combo gets noticed faster.

Practical fix for both: WebRTC — disable in your antidetect browser settings (every major one has the toggle) or block the STUN/TURN protocol at network level. DNS — bind your DNS to the proxy connection, not the system resolver; most quality proxies support this natively. Then verify with browserleaks.com or ipleak.net before trusting any session.

This won’t help. If you’re in vietnam using us proxy and you hardcode 8888 you’ll get google DNS vietnam anyway. Anycast routes you to the nearest pop.

Forcing DNS resolution on proxy side is probably the only normal strategy here.

Also when you check don’t obsess over DNS matching the carrier. Almost all real browsers don’t care about provider’s DNS recommendation, they work with their own DNS. So users on google chrome always have google DNS and so on.

Great breakdown! The distinction between WebRTC and DNS leaks is something a lot of people overlook. Most assume a green status on an IP checker means they're fully covered — but as you pointed out, they're two completely different layers of exposure.

The point about UDP proxies is underrated. A lot of people cheap out on SOCKS5 proxies and then wonder why they're still getting flagged despite having a "clean" IP. Quality of the proxy matters as much as the type.

Forcing DNS through the proxy side (remote resolution) is probably the most underused fix too. Thanks for putting this together clearly.

Please tell me Best antidetect browser name and Best Socks 5 UDP proxies provider

I would also check timezone and IPv6 together. A lot of people fix WebRTC and DNS, then forget the browser still tells a different location story somewhere else.

Mango Proxy · Jul 8, 2026

Nice write-up. I'd probably add one more point: don't treat WebRTC and DNS as separate checkboxes. Modern detection systems care much more about whether all browser and network signals are consistent than whether every individual test shows green.
