How does a VPN work?
More about VPN functionality!
A VPN is a tool to create a secure tunnel between the user and the internet. It is done by creating an encrypted tunnel in the location of the user’s choice. A VPN server works to encrypt your web traffic, hides your IP address, and prevents other third parties from spying on your browsing activities.
Internet Without VPN
The website knows who you are and what your location is. As your ISP is handling and directing all your traffic, it can also keep a check on the websites you visit, and your activity can be linked to you by your original IP address.
Internet With VPN
The VPN will hide your IP address from the websites by replacing the original IP address with the IP address of the VPN server. This IP address is shared by several users and keeps on changing regularly.
How does a VPN Hide the IP Address?
A VPN server helps you get rid of this privacy risk. When you search a website using a VPN app or software, before coming in contact with the webserver, your data and traffic reach the VPN server. The VPN server then forwards that data to the web server hosting your website.
After that, when the web server sends some information back to you, that information first goes to the VPN server and then is forwarded to you. In this way, there is no way that a website can come in direct contact with you and get access to your original IP address.

How Does a VPN Work?
The working of a VPN can also be explained and understood by the following activities done by VPN while providing a secure connection.
The encryption and decryption of data are done by using an algorithm called encryption cipher. Ciphers are linked with the keys or passwords used in the authentication process.
With an encrypted VPN service, the data remains safe, and even the local Wi-Fi operator or the internet service provider cannot see or read the data or traffic contents.
Authentication is a kind of password made of long and complex characters. It is provided to the parties who are creating a VPN tunnel between their VPN devices. Once authentication is done, it makes sure that the VPN server and the user are directly communicating, without the interference or spying of a third party. It is said that the more complex and long the characters of an authentication password, the more secure it is.
In tunneling, a VPN connects your smart devices like phones, laptops, tablets, or computers to another network while hiding your IP address and encrypts all the data generated while surfing on the internet.
By creating an indirect connection to websites through a VPN tunnel, you can protect your online activities and the IP address from hackers, government bodies, and other snoops. Tunneling is useful when you are using the internet in public, hotels, library or coffee shops.
By showing the location through the IP address of the private VPN server, the user can become more anonymous to the websites.
