What does my ISP see when I am connected to VPN?

This article is available in German, French, Japanese, Italian, Korean, Dutch, Polish, Portuguese-Brazilian, Swedish, and Spanish.

When you connect to a NordVPN server, your internet service provider (ISP) can see that you’re connected to an IP owned by a VPN service — in this case, NordVPN. It might also know the time of your connection and the port your VPN protocol is using. Plus, the provider will see the amount of traffic traveling to and from your device.

Apart from these, the only other important thing your service provider can detect is the fact that your actual online traffic is hidden from them. That means it loses access to the following information:

  • The websites you visit
  • The specific web pages you browse and the time you spend there
  • Your browsing and search history
  • The files you download from or upload to unencrypted websites
  • The info you type on unencrypted websites

Why does the ISP still see some information?

That’s because your service provider connects you to the websites you want to visit. You send it a data package, which works as a request, and the ISP sends it to the correct destination. When you connect to a VPN, you tell it to send that request to the VPN server.

But from that point on, the VPN server takes over the package, and the ISP will never know its final destination.

To sum up, the ISP sees this information when you use a VPN:

  • The IP address of the VPN server
  • The timestamp of when you connected
  • The port your VPN protocol is using
  • The amount of data you’re sending or receiving
  • Encrypted and unreadable data traveling between you and the VPN server

So use a VPN to block ISP tracking and protect your privacy
