So any websites you access will only see the VPN server IP address, and the site will consider you as being in the server’s location even though you may well be thousands of miles away. Some VPN providers, though not all, offer some of these options to their users.Ī VPN also replaces your ISP-provided IP address with the IP address of the VPN server to which you’re connected.
