Data during communication is sent in packets.
All this back and forth communication happens in an encrypted manner, so the ISP only knows the address of the VPN server, but not the webpage you have requested or the content of the data packets. The ISP forwards the request to the VPN server, which then looks up the webpage for you. Once it has found the IP address matching the domain name, the ISP will return the webpage to you.Ī VPN assumes control of that responsibility as soon as you connect to the server. A DNS server is like the phone book that contains all the domains and their respective IP addresses. If you wish to open Google, that request will first go to the ISP, who will then look up the domain name using a DNS server. You pick an Internet Service Provider (ISP) and access the internet. In the case of VPN services, a remote server allows you to connect and use it as a proxy for internet access.
You can create a private network locally between multiple devices, or you can create one through a remote server. A private network is one that is exclusive to the devices that have been given access.
