You get a plain-English result within seconds telling you whether your real IP is hidden and whether anything is leaking through.

This page explains what a VPN checker looks for, how to read the results, and what to do if something comes back wrong.

What Does a Free VPN Checker Actually Look For?

A good VPN checker runs several tests at once. Here is what each one means in plain terms.

IP Address Test

Every device on the internet has a public IP address. Think of it as your home address for the internet. When your VPN is working, websites should see the VPN server's address, not yours. A VPN checker reads your current public IP and tells you whether it belongs to a VPN provider or to your real home internet connection.

Internet Provider Check

Every IP address is registered to an organization. That organization is usually either your home broadband provider or, if your VPN is working, a data centre or VPN company. A VPN checker looks up who owns your IP and tells you the result. If you see your real broadband provider's name, your VPN has a DNS leak and your provider can still see where you browse.

Location Check

Your IP address gives websites a rough idea of where you are. When your VPN is working, the location shown should match the VPN server's location, not where you physically are. If you connected to a server in Germany, the checker should show Germany. If it shows your real city, your connection is not going through the VPN correctly.

WebRTC Leak Check

WebRTC is a feature built into web browsers for video and voice calls. The problem is that it can reveal your real IP address to websites even when your VPN is turned on. Our checker tests for this automatically and flags it if your browser is leaking your real location through WebRTC.

How to Read Your VPN Check Results

Green Result: Your VPN Is Working

The IP address shown is different from your real one. The provider name belongs to a VPN company or data centre. The location matches the server you chose. No WebRTC leak was found. This is exactly what you want to see.

Red Result: Your VPN Is Not Working or Is Leaking

Something has gone wrong. Either your real IP is showing, your broadband provider's name appears, or your real location is visible. The result will tell you which check failed so you know where to focus your fix.

Unknown Provider

Sometimes the provider name comes back as "Unknown." This is not necessarily a problem. It can happen when the VPN uses an IP range that is not in public databases yet, or when a newer provider's details have not been catalogued. Check the other fields. If the location and IP both look correct for your chosen VPN server, you are likely fine.

Reasons a VPN Check Might Fail Even Though Your App Looks Connected

The most common reason is a DNS leak. Your VPN tunnel is open, but the requests that convert website names to addresses are still going to your internet provider instead of through the VPN. Your provider can see every website you visit.

Another common reason is split tunnelling. This is a VPN feature that lets some apps bypass the VPN. If your browser is set to bypass the VPN in split tunnelling settings, the checker will show your real IP because your browser is genuinely not using the VPN.

WebRTC leaks are the third common cause. Your main IP might be hidden but your browser is still exposing your real address through its built-in WebRTC feature. Our checker catches this and flags it separately.

What to Do After Running the Check

If the result is green, you are good. Run the check again after your next VPN update or device restart to make sure nothing changes.

If the result shows a problem, start with these steps:

  • Disconnect and reconnect your VPN
  • Try a different server location
  • Open your VPN app settings and look for a DNS leak protection option. Turn it on.
  • Restart your device and run the check again
  • If the problem is WebRTC, install the uBlock Origin browser extension and enable WebRTC blocking in its settings

If none of those steps fix the issue, the VPN service itself may have reliability problems. Switching to a more trusted provider is worth considering.

Are All Free VPN Checkers the Same?

No. Some checkers only look at your IP address. That gives you a partial picture. Our tool runs an IP check, a DNS provider check, a location check, and a WebRTC leak detection simultaneously. You get a complete status in one result rather than needing to visit four different sites.

The key thing to look for in any VPN checker is whether it tests DNS separately from the IP address. Those are two different things. A VPN can hide your IP while still leaking your DNS, and a checker that only looks at the IP will give you a false pass.
