Do I get a different IP address every time?

Each GOOSE VPN server has its own IP address. So, you can change the IP address at any time by connecting to another server.

The servers each have a different IP address to ensure that the IP address from which you access the internet (with the VPN on) is the same as the country of the server you selected. Do you switch off GOOSE VPN again? Then you are online with your own IP address again.
