Introduction
Even if you’re using a VPN or proxy, your real IP address can still be exposed through an IP leak. This leaves you vulnerable to tracking, hacking, and surveillance.
In this blog, we’ll explain what an IP leak is, how it happens, and how to prevent it.
What Is an IP Leak?
An IP leak occurs when your real IP address is accidentally revealed despite using tools to hide it.
For example:
-
You connect to a VPN → VPN assigns a new IP.
-
But due to browser, DNS, or WebRTC leaks, your real IP is still visible.
Types of IP Leaks
1. DNS Leaks
Your device sends DNS requests directly to your ISP instead of the VPN, exposing your IP.
2. WebRTC Leaks
Browsers using WebRTC can accidentally reveal your local IP to websites.
3. IPv6 Leaks
If your VPN doesn’t support IPv6, your IPv6 address may bypass protection.
Why IP Leaks Are Dangerous
-
Expose your true location
-
Allow hackers to track your activity
-
Bypass VPN protections
-
Risk of data theft and identity exposure
How to Check for IP Leaks
-
Use online IP leak test tools
-
Disconnect VPN to compare addresses
-
Look for DNS requests outside the VPN
How to Prevent IP Leaks
-
Use a reliable VPN with DNS & IPv6 leak protection.
-
Disable WebRTC in your browser.
-
Regularly run IP leak tests.
-
Use a firewall to block non-VPN connections.
Final Thoughts
An IP leak can undo all your privacy efforts. Always use a trustworthy VPN, configure your browser correctly, and test for leaks regularly.
