How to Check if a VPN Is Working
Using a VPN (Virtual Private Network) is generally straightforward. Just open the app and press “Connect.” However, even if the app shows you’re connected, your VPN might not function properly. For instance, we once found that a VPN didn’t fully hide our real IP address, preventing us from accessing Netflix Japan. To avoid issues like this, it’s essential to test if your VPN is operating as it should. Learn more about VPN IP address check for enhanced security
Key Tests to Perform
DNS Leak Test
What is it?
DNS (Domain Name System) changes website names into IP addresses. When you use a VPN, it should keep your DNS requests private. If there’s a leak, your Internet Service Provider (ISP) can still see your real IP address.
How to Test:
- Disconnect your VPN.
- Use an IP checker (like What Is My IP?) to find your real IP address.
- Connect to your VPN again.
- Visit a DNS leak test website (such as DNSLeakTest.com) and run the test.
- Check if the IP shown matches your real IP. If it does, your VPN has a DNS leak.
WebRTC Leak Test
What is it?
WebRTC (Web Real-Time Communication) allows direct communication between devices, which can inadvertently reveal your real IP address if your VPN isn’t blocking it properly.
How to Test:
- Follow the same initial steps as in the DNS test.
- Use a WebRTC leak test tool (like the one from ExpressVPN).
- Compare the IP displayed with your actual IP. If they match, your VPN isn’t working effectively.
Streaming Test
Many users employ VPNs to access content that isn’t available in their region, such as shows on Netflix or Hulu. After confirming zero leaks, check whether your VPN can stream services without issues. If you see a message indicating that you’re using a proxy, try switching servers or consider choosing a different VPN known to work with the service.
Malware Check
Some free VPNs may contain malware that can harm your device. To ensure your VPN is safe, run a malware scan using reliable antivirus software.
How Often to Test
It’s wise to perform DNS and WebRTC leak tests regularly, especially before engaging in activities that require privacy. Streaming tests are useful before planning a binge-watching session.
Why Leaks Happen
Leaks may suggest that:
- Your VPN connection isn’t stable.
- The VPN itself has issues with its encryption methods.
- Your operating system or browser has vulnerabilities.
Troubleshooting VPN Issues
If your VPN isn’t functioning properly, consider these steps:
- Check your internet connection.
- Try connecting to a different server.
- Ensure your login details are correct.
- Disable the firewall or antivirus temporarily to see if they interfere.
Benefits of Using a VPN
VPNs enhance your online safety by:
- Protecting your information on public Wi-Fi.
- Allowing access to international content.
- Helping you bypass regional restrictions on websites.
