How to Check if VPN is Working?
🔍 Quick answer:
To check if your VPN is working, run these 4 tests: 1) IP check — visit whatismyip.com. If the location matches your VPN server (not your real location), your IP is hidden. 2) DNS leak test — visit dnsleaktest.com and run the extended test. Only VPN DNS servers should appear. 3) WebRTC leak test — visit browserleaks.com/webrtc. No real IP should be displayed. 4) Kill switch test — disconnect your VPN. If your internet stops working, the kill switch is active. If all tests pass, your VPN is working correctly.
4 tests to check if your VPN is working
Test 1: IP address check
Visit whatismyip.com or ipleak.net. Your IP address and location should match the VPN server you're connected to — NOT your real location. If you see your real city/ISP, your VPN is NOT working.
Test 2: DNS leak test
Go to dnsleaktest.com → Run the extended test. You should only see DNS servers belonging to your VPN provider. If you see your ISP's DNS servers (like Comcast, Verizon, AT&T), you have a DNS leak.
Test 3: WebRTC leak test
Visit browserleaks.com/webrtc. WebRTC is a browser technology that can expose your real IP even through a VPN. If you see your real IP listed, you have a WebRTC leak. Fix by disabling WebRTC or using a browser extension.
Test 4: Kill switch test
Temporarily disconnect your VPN (or force-close the VPN app). If your internet instantly stops working, your kill switch is active. If you can still browse, your kill switch is NOT enabled — enable it in your VPN app settings.
Quick checklist: Is my VPN working?
| Test | Pass (VPN working) | Fail (VPN not working) |
|---|---|---|
| IP address | Shows VPN server location | Shows your real location/ISP |
| DNS test | Only VPN provider DNS servers | Your ISP's DNS servers appear |
| WebRTC test | Only VPN IP shown | Your real IP appears |
| Kill switch | Internet stops when VPN disconnects | Internet continues when VPN drops |
💡 Pro tip: Run these tests after every VPN install and periodically afterward. A VPN can appear connected while still leaking your real IP through DNS or WebRTC — testing ensures you're actually protected. Bookmark these test sites: whatismyip.com, dnsleaktest.com, and browserleaks.com/webrtc.
