Does a VPN Actually Change Your IP Address?

The short answer is: a VPN changes the IP address websites see, but it does not change the IP address assigned to your actual internet connection. That distinction matters more than the marketing slogans suggest.

What an IP address actually is

Your IP address is an identifier assigned to the network connection you are using at that moment. When you are connected to your home broadband, your Internet Service Provider assigns your router a public IP address. When you use mobile data, your mobile operator assigns a different one. When you connect to a VPN server, the VPN service assigns you the IP address of that server.

The key point is that the address is tied to the network path your traffic takes, not to you personally. Switch networks, and the IP changes. Route traffic through a VPN, and the IP websites see changes too, because your traffic now exits from the VPN server.

What a VPN actually does

A VPN does not rewrite the IP address your ISP assigned to your home connection. That assignment stays exactly as it was. What the VPN does is create an encrypted tunnel between your device and the VPN server, and route your internet traffic through that server first. When a website receives a request from you, it sees the VPN server’s IP address, not your home IP address.

Your device’s real IP has not been “changed” in the sense of replacing it. It has been masked from the sites and services you visit. The VPN server is now the public-facing hop between you and the internet.

Why people say their IP “changed”

From the website’s point of view, your IP really does change. Connect to a VPN server in London and a website sees a London IP. Disconnect and reconnect to a server in New York, and the same site sees a New York IP. That is real and useful. It is why a VPN can help you appear to be browsing from a different country, and why it can reduce the location information sites collect about you.

The confusion comes from mixing up two different things: the IP assigned to your connection by your ISP, and the IP visible to the rest of the internet. A VPN changes the second one. The first one remains unchanged unless you restart your router, switch networks, or ask your ISP for a new assignment.

What a VPN does not hide

A VPN is not a switch that makes you invisible. Your ISP can still see that you are connected to a VPN server. It cannot see what you are doing inside that tunnel if the VPN is properly encrypting your traffic, but the connection to the VPN server itself is visible. Without a VPN the picture is wider, and what your ISP can actually see sets out which parts survive encryption.

Logins, cookies, browser fingerprinting, and the accounts you sign into can still identify you even when your IP is masked. If you sign into Google or Facebook while connected to a VPN, those services still know it is you. A VPN also does not remove trackers from websites, block ads by default, or protect you from malware. It is a privacy tool for your network traffic, not a complete anonymity solution.

How to verify it is actually working

You can check the before-and-after yourself. Visit the My IP Address page before you connect to the VPN and note the IP and location it shows. Then connect your VPN, refresh the page, and check again. The visible IP should now match the VPN server location instead of your home ISP.

For a broader check, use the Is My VPN Working? page. Then run the Network Leak Check and the WebRTC Leak Test to confirm that no traffic is leaking outside the tunnel. If either test shows your real ISP details, your VPN setup needs attention.

Is a VPN the right tool for you?

If your goal is to stop websites seeing your home IP address, reduce location exposure, or add a layer of privacy on public Wi-Fi, a reputable VPN can help. The key is to choose a provider with a strong no-logs policy, working leak protection, and servers where you need them. For one option we have reviewed, see our NordVPN review.

A VPN does not “change” your IP address in the literal sense, but it does change the IP address the internet sees. That is enough for most privacy use cases, as long as you understand what it does not do.
