Is Your VPN Really Protecting You? 5 Tests to Find Out

Start with a quick visit to whatismyip.com - you'll instantly see if your VPN is working. Your IP address, country, city, and ISP should all match your VPN location, not your real ones. If you see your actual details, your VPN isn't protecting you.

For a deeper check, your VPN might be leaking your real location in other ways. Before and after connecting to your VPN, visit ipleak.net. Check both IPv4 and IPv6 addresses - many VPNs only protect one, leaving the other exposed. If you see your actual IP address instead of your VPN's location, your data is exposed.

Run an IP test monthly - expect to see only your VPN's location, not your actual address for both IPv4 and IPv6

Your browser might bypass your VPN when looking up websites, exposing your browsing history. Visit dnsleaktest.com and run the extended test. If you see your internet provider's servers instead of your VPN's, your activity is visible. Enable your VPN's DNS leak protection feature or manually configure your DNS servers to your VPN provider's addresses.

Run the extended DNS test weekly - all servers should match your VPN provider

Video calls can reveal your real IP even with a VPN. Visit browserleaks.com/webrtc to check for WebRTC leaks. If you see your actual IP, disable WebRTC in your browser settings or install a WebRTC blocking extension for additional protection. This prevents video apps from exposing your location.

Use official desktop apps. If you’re concerned about your IP while using Zoom, Microsoft Teams, or Slack, consider using their dedicated desktop apps. These can minimize the risk of WebRTC-based leaks that occur in-browser.

A properly configured VPN should only slow your connection by 10-20%. Run a speed test at speedtest.net with the VPN off, then on. Test multiple server locations - speeds can vary significantly based on distance and server load. If speed drops more than 30%, try switching to a closer server or a less congested location.

Even if your VPN passes all tests, an unexpected connection drop could expose your real IP unless your VPN has a reliable kill switch. Also, confirm your VPN has a no-logs policy to ensure your activity isn’t being recorded.

Visit surfshark.com/dns-leak-test with your kill switch enabled, then force-close your VPN. Your internet should immediately disconnect.

Enable the kill switch – it blocks internet traffic if the VPN connection drops.
Choose a no-logs provider – prevents your activity from being stored on servers.
