7 Signs Your VPN is Leaking Your Real IP Address Right Now

Most VPN failures are invisible. Your VPN app continues to display its reassuring green icon, the connection status reads "connected," and you carry on browsing under the assumption that your real identity is hidden. But there are tell-tale signs that something is wrong — signs that your real IP address, location, or browsing activity is leaking through the cracks of a VPN connection that is failing to do its job. Here are seven of the most revealing indicators.

Sign 1: IP Check Tools Show Your Real ISP's Name

This is the clearest possible sign that your VPN is leaking. When you run an IP address check — like our free tool — the ISP or organisation name displayed should belong to a VPN provider or data centre company, not your home internet provider. If you see "Comcast", "BT", "Vodafone", "Verizon", or any other consumer ISP name while your VPN claims to be connected, your traffic is not actually routing through the VPN server. Your real IP is fully exposed.

The fix: disconnect and reconnect to your VPN. Try a different server. If the ISP name still shows your home provider, the VPN app is not routing traffic correctly and you should contact your provider's support team.

Sign 2: Geo-Restricted Content You Should Be Able to Access Is Still Blocked

One of the most practical tests for VPN functionality is trying to access content that is restricted to a specific country. If you connect to a VPN server in the United States and try to access US-only streaming content that remains unavailable, or you connect to a UK server and BBC iPlayer still says you are not in the UK, your VPN is either not routing correctly or the streaming service has blocked the VPN server's IP range. Either way, it is a sign to investigate further with an IP check tool.

Sign 3: Geo-Restricted Content You Should NOT See Is Still Accessible

This one works in reverse. If you are connected to a VPN server in another country, you should see that country's version of websites and services — not your home country's version. If you connect to a German server but Netflix still shows your home country's library, or your bank's website still shows content localised for your real location, something is routing incorrectly. The site is seeing your real location, not your VPN server's location.

Sign 4: IP Check Shows Your Real IP Address (The Obvious One)

If you visit an IP address check website while your VPN is connected and it shows the same IP address you have without the VPN, your VPN is completely failing to mask your identity. This is total VPN failure — not a partial leak. Your IP address should be completely different when the VPN is active, belonging to the geographic location of the server you selected in the VPN app. Same IP before and after connecting means the VPN tunnel is not working at all.

Sign 5: WebRTC Leak Test Reveals Your Home IP

WebRTC (Web Real-Time Communication) is a browser technology used for video calls, voice calls, and peer-to-peer file sharing. The problem is that WebRTC has a mechanism for discovering the network interfaces on your device, and it can reveal your real IP address to websites even when you are connected to a VPN. This happens because WebRTC communications can bypass the VPN tunnel entirely by communicating directly via UDP.

A WebRTC leak is particularly insidious because your main IP address check will show the correct VPN IP — suggesting you are protected — while a WebRTC-specific check reveals your real IP running alongside it. Our VPN check tool tests for this automatically. If your real home IP appears in WebRTC results, install a browser extension that blocks WebRTC leaks immediately.

Sign 6: DNS Requests Show Your ISP's DNS Servers

Even if your IP address is correctly masked by the VPN, your DNS queries — the requests your device makes to translate domain names like google.com into IP addresses — might still be going to your Internet Service Provider's DNS servers instead of through the VPN tunnel. This is called a DNS leak, and it means your ISP can see every domain name you query, effectively giving them a complete log of every website you visit despite your VPN appearing to work.

Signs of a DNS leak include: the ISP name shown in IP check tools is your home provider; dedicated DNS leak test tools show DNS servers belonging to your ISP; and you notice websites serving you localised content based on your real location rather than your VPN server's location.

Sign 7: Your VPN's Kill Switch Never Activates — Even During Connection Drops

A kill switch is a critical VPN feature that automatically blocks all internet traffic if the VPN connection drops, preventing your real IP from being exposed during the gap between disconnection and reconnection. If you have never seen your kill switch activate — especially if you are a regular VPN user who has experienced occasional connection drops — this might indicate the kill switch is not configured correctly or is disabled.

To test your kill switch: connect to your VPN, then deliberately cause a brief network interruption (such as disabling and re-enabling Wi-Fi). During that moment, your internet should be completely cut off if the kill switch is working. If websites continue to load during a VPN disconnection, your kill switch is not active and your real IP is exposed every time the VPN drops.

What to Do If You Spot These Signs

First, run a comprehensive check using our free VPN test tool to understand exactly what is leaking. Then:

• For IP leaks: reconnect to a different server or reinstall your VPN app
• For DNS leaks: enable "DNS leak protection" in your VPN settings
• For WebRTC leaks: install uBlock Origin and enable WebRTC blocking
• For kill switch issues: find the kill switch in your VPN app settings and ensure it is enabled
• If multiple leaks persist: consider switching to a more reliable VPN provider
