Quick Answer
Yes, a VPN changes your IP address, but it doesn't permanently replace it. Instead, a VPN acts as a secure middleman. It temporarily hides your real IP address by routing your internet traffic through a remote server, making websites think you have the IP address of that server.

To truly understand how a Virtual Private Network protects your privacy, it helps to visualize the step-by-step journey your data takes when you turn a VPN on versus when it is off.
How the Internet Works Without a VPN
- You type a website into your browser and press Enter.
- Your device sends a request packet to your Internet Service Provider (ISP), stamped with your real, public IP address.
- Your ISP forwards this request to the website's server.
- The website's server reads your real IP address to know where to send the webpage back to.

How the Internet Works With a VPN
- You open your VPN app and connect to a server in a different location (e.g., London).
- Your VPN app encrypts your data request. It still goes through your ISP, but because it's encrypted, your ISP cannot read what website you are trying to visit.

- The VPN server decrypts the data and forwards the request to the website.
- The website's server only sees the London VPN server's IP address—it has absolutely no record of your real IP.

What this reveals / Why it matters
The fact that a VPN changes your visible IP address matters tremendously for three core reasons: privacy, security, and accessibility.
Because your IP address is effectively your digital home address, hiding it breaks the tracking mechanisms used by advertising agencies and data brokers. They can no longer easily map your browsing habits to your physical location. Secondly, changing your IP address enhances security. If a malicious hacker tries to launch a targeted attack against the IP address they see on a multiplayer game or P2P network, they will end up attacking the VPN's highly fortified server instead of your vulnerable home network.
Finally, it restores accessibility to a fractured internet. Streaming platforms, news sites, and even authoritarian governments block content based on the geographic location tied to an IP address. By using a VPN to change your IP address to a different country, you instantly bypass these digital borders.
How to protect yourself
While all VPNs claim to change your IP address, not all of them do it securely. Free VPNs often suffer from browser leaks, where your real IP address occasionally slips out alongside the fake one, rendering the service useless.
To ensure your IP address remains completely hidden, you need a premium service that controls its own servers and implements strict leak protection. The easiest way to hide your real IP address is a VPN. NordVPN is the most reliable option — it also blocks WebRTC leaks by default which most VPNs miss. Get NordVPN here.

Frequently Asked Questions
Does a VPN change my IP address permanently?
No. A VPN only temporarily masks your IP address while the VPN application is actively connected. Once you disconnect, your traffic reverts back to using your real IP address assigned by your ISP.
Can my internet provider still see my real IP when I use a VPN?
Your ISP assigned your real IP, so they always know it. However, when using a VPN, your ISP can only see that you are connected to a VPN server; they cannot see which websites you visit or the data you download.
Why do some websites block my VPN IP address?
Because VPN servers are shared by thousands of users, their IP addresses often end up on blacklists maintained by streaming services like Netflix, which block them to enforce regional licensing agreements.
