Can a VPN Hide Your IP Address? What Really Happens

Yes, a VPN can hide your IP address. That is one of its core functions. But the honest answer has a few important conditions. Sometimes a VPN hides your IP partially but leaks it through other channels. Sometimes it hides your main IP but exposes a second address that gives away your location. Understanding how this works takes about five minutes and could save you from a false sense of security.

What Is an IP Address and Why Does It Matter?

Your IP address is a number assigned to your internet connection by your provider. It identifies your connection on the internet the same way a postal address identifies a building. Every website, app, and online service you connect to can see your IP address. They use it to determine your rough location, identify you across sessions, and in some cases restrict what content you can access based on your country.

Without any protection, your real IP address is visible to every website you visit, to every app you use that connects to the internet, and to your internet provider, who can see everything you do online.

How a VPN Hides Your IP Address

When you connect to a VPN, your device creates an encrypted connection to a server operated by the VPN company. From that point on, all your internet traffic travels through that server before reaching its destination. Websites and services see the VPN server's IP address, not yours. Your real IP never reaches them directly.

Think of it like sending a letter through a forwarding service. You send your letter to the forwarding address. They open it, put it in a new envelope with their address as the return, and send it on. The recipient never sees where it originally came from.

When a VPN Does Not Fully Hide Your IP

There are several situations where your real IP can still be visible even with a VPN connected.

WebRTC Leaks

Web browsers have a built-in feature called WebRTC that is used for video calls, voice calls, and other real-time communication. WebRTC works by establishing direct connections between devices, and as part of this process it can expose your real IP address to websites, even through a VPN. The website's code can request your IP via WebRTC, and your browser responds with your real address without the VPN intercepting it.

This is one of the most common reasons people think their VPN is working when it is not. The main IP check passes, but a WebRTC check reveals the real address running underneath. Our free tool tests for this automatically.

IPv6 Leaks

Most internet connections use a system called IPv4 for addresses. But many modern connections also have a second address system called IPv6 running alongside it. If your VPN only protects IPv4 traffic and ignores IPv6, your IPv6 address travels to websites unprotected. Websites that support IPv6 can see your real IPv6 address and use it to identify your real location and internet provider.

DNS Leaks

Even if your visible IP address is successfully hidden, your DNS requests may still go to your internet provider. DNS is what converts website names into server addresses. If those requests bypass the VPN, your provider can see every website you visit. Your IP is hidden from websites, but your browsing history is not hidden from your provider.

Split Tunnelling Mistakes

Many VPN apps include a feature called split tunnelling that lets specific apps bypass the VPN. If your browser is accidentally set to bypass the VPN in split tunnelling settings, your real IP is fully visible to every website you visit through that browser, even though other apps on your device are protected.

How to Verify Your IP Is Actually Hidden

The only reliable way to confirm your VPN is hiding your IP is to run a test. Here is the manual method:

1. Disconnect your VPN
2. Visit our homepage and note the IP address shown. This is your real IP.
3. Connect your VPN to a server in any country
4. Reload the page
5. The IP shown should now be completely different and should belong to the country you selected
6. The provider name shown should be a VPN company, not your home broadband provider

Our tool also automatically tests for WebRTC leaks, which means you get a full picture in one check rather than needing to visit multiple sites.

What a Hidden IP Does Not Protect You From

It is worth being clear about this. Hiding your IP address is useful, but it is not total protection. Websites still know you visited if you are logged into an account. Cookies still track you across sessions. Browser fingerprinting can still identify your device without using your IP at all. A VPN improves your privacy significantly, but it does not make you untraceable.

The Bottom Line

A good VPN, properly configured, does successfully hide your real IP address from websites and services. But the words "properly configured" matter. DNS leak protection needs to be enabled. IPv6 coverage needs to be active. WebRTC needs to be blocked at the browser level. And you need to verify all of this is working rather than trusting the connected status in the app.

Our free tool checks all of this at once and gives you a clear result in under 10 seconds.
