What Is a VPN?
VPN stands for Virtual Private Network. It creates an encrypted tunnel between your device and a remote server operated by the VPN provider. All your internet traffic passes through this tunnel, which does two key things: it encrypts your data so nobody between you and the server can read it, and it replaces your real IP address with the VPN server's IP address.
How Does a VPN Change Your IP?
You can verify this by checking your IP on our IP lookup tool before and after connecting to a VPN. The IP address, location, and ISP should all change to reflect the VPN server's details.
Why Use a VPN?
- Privacy: Hide your real IP and location from websites, advertisers, and trackers.
- Security on public Wi-Fi: Encrypt your connection on coffee shop, airport, and hotel networks.
- Bypass restrictions: Access content that may be blocked in your region or network.
- Prevent ISP tracking: Stop your ISP from monitoring and potentially selling your browsing activity.
What a VPN Does NOT Do
A VPN does not make you completely anonymous — it's one layer of privacy, not invisibility. It doesn't protect you from malware, phishing, or viruses. It doesn't make illegal activity legal. And it can slow your connection slightly due to the extra routing and encryption.
Choosing a VPN
The most important factors are a strict no-logs policy (independently audited), fast server speeds, a large server network, and support for all your devices. We recommend NordVPN — it checks all these boxes with 6,400+ servers across 111 countries and has been independently audited for its no-logs policy.
How to Test If Your VPN Is Working
After connecting to your VPN, visit our IP lookup tool. If the VPN is working correctly, you should see the VPN server's IP address and location — not your real ones. If you see your actual city and ISP, the VPN connection may not be active.
