Why IP address leaks are a serious privacy risk

An IP address is like your home address for the internet; it reveals your approximate location and can be used to track your online activity. When your VPN fails to mask it, your internet service provider (ISP), websites, and even hackers can see exactly who you are and where you're browsing from. This defeats the entire purpose of using a VPN for privacy or security.

Common consequences of an IP leak include targeted advertising, throttled internet speeds from your ISP, and in severe cases, exposure to cyberattacks or legal trouble if torrenting. Regularly checking for leaks is non-negotiable for anyone serious about their online anonymity.

How to check for IP leaks: a step by step guide

Thankfully, verifying your VPN's integrity is straightforward. Follow these steps to ensure your real IP isn't exposed.

Step 1: Disconnect your VPN and note your real IP

First, turn off your VPN completely. Visit a reliable IP checking website like IPLeak.net or DNSLeakTest.com and note the IP address and location shown. This is your baseline real IP information.

Step 2: Connect to your VPN server

Reconnect to your VPN, choosing a server in a different country than your own for a clear test. Wait until the connection is fully established.

Step 3: Run a comprehensive leak test

Return to the leak testing website with your VPN active. A trustworthy VPN should now show a different IP address and location matching the server you selected. Crucially, run tests for:

• IPv4 Leak: The most common type; ensure the displayed IPv4 isn't yours.
• IPv6 Leak: Many VPNs still don't handle IPv6 well; check that it's either blocked or showing the VPN's IP.
• DNS Leak: Your DNS requests should be routed through the VPN's servers, not your ISP's. The test should show the VPN's DNS provider.
• WebRTC Leak: This browser vulnerability can expose your IP even with a VPN active. Good leak test sites check for this automatically.

If any test reveals your original IP or ISP information, your VPN is leaking.

What to do if your VPN is leaking

Don't panic if you discover a leak. First, try reconnecting to a different server within the VPN app. Sometimes, a single server can have a temporary issue. If the leak persists, check your VPN's settings for a built-in leak protection feature, often called a “kill switch.” Ensure this is enabled, as it will block all internet traffic if the VPN connection drops unexpectedly.

For persistent DNS leaks, try manually configuring your device to use a secure DNS provider like Cloudflare (1.1.1.1) or Google (8.8.8.8). However, the simplest and most effective solution is often to switch to a VPN provider with a proven no-leak guarantee.

Choosing a VPN that won't leak your IP

Not all VPNs are created equal. The best services build leak protection directly into their apps, making it automatic and foolproof. Look for providers that offer:

• A reliable kill switch on all platforms
• Full IPv6 and DNS leak protection
• Transparent, independent audit reports

Based on our rigorous testing, one provider consistently excels in all these areas.

Advanced testing and tools

For users who want to go beyond basic web tests, consider downloading tools like Wireshark to analyze your network traffic directly. You can also use torrent clients to check for IP leaks specifically in peer-to-peer environments, as some VPNs may only leak during certain activities. Remember, consistent testing across different activities is key to ensuring complete privacy.
