The VPN app on your device connects you to the internet when you use a VPN. A VPN client also referred to as a VPN client, creates a secure connection by way of a VPN server. Your ISP will still be the conduit for your internet traffic, but it won't be able to read or view the endpoints. The websites you visit won't be able to view your actual IP address at the same time. Along with just the VPN server's IP address, which is shared by many other users and is dynamic. This is very easy and safe to use.
