Answer 3

To use a VPN, a VPN client is required — software that grants access to a VPN by establishing a remote, encrypted connection to a VPN server. When the VPN is active, your device’s internet traffic is encrypted and sent through your ISP’s network, meaning it cannot be understood by them, to the VPN server. From there, the VPN server forwards the traffic to its final destination on the internet. During this process, you’re assigned a new IP address by the VPN, which is the one visible to websites and online services — effectively masking your real IP address.
