"Your ISP can see your IP address and therefore knows who you are. The VPNconnection will hide your IP so that the only IP they can see is the VPN server IP.VPNs create private tunnels that are encrypted. This ensures that no one can see what websites or servers you were exchanging data with." vpnexpress.net
