Does a VPN Hide Your IP Address?

It is the single most common reason people install a VPN: to hide their IP address. So it is worth answering the question directly, then explaining where that protection quietly breaks.

The short answer is yes, with a real catch. A VPN hides your IP from the websites you visit, but small leaks can betray your true address. This guide shows you how to check.

Does a VPN Hide Your IP Address?

Yes. A VPN hides your public IP address from the websites and services you visit. Your traffic exits the VPN server wearing its IP, not yours. The catch is that DNS, WebRTC, and IPv6 leaks can still expose your real address if the VPN is misconfigured.

When you connect, your VPN builds an encrypted tunnel to a server you choose. Every site you reach sees that server’s public IP address.

Your real address stays behind the server, hidden from the destination. This is the core privacy benefit, and for most traffic it works exactly as advertised.

To understand why this matters, it helps to know the difference between public and private IP addresses. The address a VPN hides is your public one. For the full picture of how the tunnel itself works, see our guide to what a VPN is.

What a VPN Hides — and What It Still Reveals

A VPN hides your public IP and your browsing destinations from your internet provider. It does not hide your identity. Cookies, logins, and browser fingerprinting still track you. Your VPN provider can also see your real IP, so its no-logs policy is what protects you there.

It helps to separate what a VPN genuinely hides from what it leaves exposed.

What it hides:

• Your public IP address from the websites you visit.
• Your browsing destinations from your internet provider.
• Your traffic from anyone snooping on local or public Wi-Fi.

What it still reveals or cannot hide:

• Your identity, if you log into accounts or accept cookies.
• Your real IP from the VPN provider itself, which is why no-logs matters.
• Your device through browser fingerprinting, which ignores your IP entirely.
• The fact that you are using a VPN, which your ISP can still detect.

How to Check If Your VPN Is Hiding Your IP

To check, look up your public IP with the VPN off and write it down. Then connect to the VPN and look it up again. If the address changed to your server’s region, the tunnel works. Your real IP is now hidden from websites.

Never assume. This first test takes under a minute and proves the basic tunnel is live.

1. Disconnect the VPN. Open our What Is My IP Address tool and note your real public address.
2. Connect the VPN. Choose a server, then reload the same tool.
3. Compare. The address should now differ from your real one and match the server region.

If the address never changes, the tunnel is not active. That points to a connection problem or a broken VPN app, not a leak.

If it does change, the basic test passed. But a changed IP alone does not rule out the quieter leaks covered next.

IP Leaks That Can Expose Your Real Address

Three leaks can expose your real IP even with a VPN on. DNS leaks send name lookups to your ISP outside the tunnel. WebRTC leaks let your browser reveal your IP through a peer-to-peer feature. IPv6 leaks slip your IPv6 address around a tunnel built only for IPv4.

A changed IP can hide a leak underneath it. These three are the ones that matter.

DNS leaks

Every site you visit starts with a DNS lookup that turns a name into an IP. A leak sends that lookup to your ISP instead of through the tunnel.

The site may see the VPN’s IP, but your ISP still logs every domain you request. Knowing how DNS works makes this easy to spot.

WebRTC leaks

WebRTC is a browser feature for real-time calls and chat, enabled by default since around 2013. To connect devices directly, it can ask a STUN server for your real IP.

That request can travel outside the tunnel and hand your true address to a tracking script. This is the most common and most overlooked leak.

Chromium browsers like Chrome, Edge, and Brave cannot fully disable WebRTC in their settings. Modern browsers do hide local IPs using mDNS, but the public-IP risk remains without protection.

IPv6 leaks

Many VPNs were built to tunnel IPv4 traffic only. If your network also uses IPv6, that traffic can slip around the tunnel.

The result is an exposed IPv6 address while your IPv4 looks safely hidden. Our IPv4 vs. IPv6 guide explains why both must be covered.

How to Test for IP Leaks

Test for leaks in two passes. First confirm your public IP changed using an IP tool with the VPN on. Then run a dedicated leak test that checks DNS, WebRTC, and IPv6 separately. If any of those still show your real IP or your ISP, you have a leak.

A complete test goes beyond the public IP. Run through each layer.

• Public IP: Confirm it changed with our IP address tool while connected.
• DNS: Check that lookups route through the VPN, not your ISP. Our DNS lookup tool helps you read the results.
• WebRTC: Use a WebRTC leak test in the same browser you actually use. Each browser behaves differently.
• IPv6: Confirm no IPv6 address appears outside the tunnel, especially on a dual-stack network.

Test in the browser and device you use daily. A profile that is safe in one browser can still leak in another.

Who Can Still See Your Real IP Address

Even with a working VPN, a few parties still see your real IP. Your VPN provider always knows it. Your internet provider assigns it and sees you connecting to a VPN. Anyone exploiting a leak can grab it too. A VPN narrows who sees your IP, but never to nobody.

Hiding your IP from websites is not the same as hiding it from everyone.

• Your VPN provider: It receives your real IP to route your traffic. A verified no-logs policy is what keeps that safe.
• Your internet provider: It assigns your real address and can see you connecting to a VPN server.
• Leak exploiters: A site using WebRTC or a DNS trick can grab your real IP if protection fails.
• Legal requests: A provider may be compelled to share data, though no-logs providers have little to hand over.

How to Stop IP Address Leaks

Stop leaks by choosing a VPN with a kill switch, DNS leak protection, and built-in IPv6 handling. Enable WebRTC protection in your VPN app or browser. Then retest after any change. The goal is a tunnel that covers every layer, not just your public IPv4 address.

Most leaks have a clean fix. Work through this short list.

• Use a kill switch: It cuts your internet if the VPN drops. Your real IP never leaks during a reconnect.
• Turn on DNS leak protection: This forces DNS queries through the tunnel. Most reputable VPNs include it.
• Handle IPv6: Pick a VPN that tunnels or disables IPv6 so it cannot slip around the connection.
• Block WebRTC: Use a VPN that stops WebRTC leaks, or disable the feature in your browser settings.
• Retest: Run the leak checks again after changing any setting or updating your browser.

If you are still stuck after these steps, the issue may be your connection rather than the VPN. Our connectivity troubleshooting guide can help.
