Private network connections are established using a layer of an encrypted tunneling protocol and authentication methods such as entering a password or certificate to ensure security. In addition, the VPN function is for internet users who want to secure their personal identities to remain anonymous on the internet.
As we know there are some websites that can’t be opened like Reddit in some countries. However, users can still open it through the VPN. VPNs are created by establishing point to point virtual connections through the use of dedicated circuits with tunneling protocols on existing networks. VPN itself has its own types.
Basically, VPN creates a network within a network which is often also called tunneling. Tunneling has the aim to make a personal connection line that utilizes a different network.
