How VPNs Work: The Basics
What is a VPN?
A VPN, or Virtual Private Network, is a technology that allows you to create a secure, encrypted connection to another network over the internet. It acts as a protective shield for your online activities, making it difficult for anyone to intercept your data or track your online behavior. VPNs are commonly used for various purposes, such as ensuring online privacy, accessing geo-restricted content, and enhancing security on public Wi-Fi networks.
Encryption and Tunneling
At the core of how VPNs work is encryption. When you connect to a VPN server, your internet traffic is encrypted, meaning it’s transformed into unreadable code. This encryption ensures that even if someone intercepts your data, they won’t be able to make sense of it.
The VPN also establishes a secure connection, often referred to as a tunnel, between your device and the VPN server. This tunnel ensures that your data is transmitted securely over the internet, protecting it from prying eyes.
IP Address Masking
One of the key features of a VPN is IP address masking. When you connect to a VPN server, your real IP address is hidden, and the server assigns you a new one. This new IP address can be from a different geographic location, making it appear as though you are browsing from another region or country. This feature is particularly useful for bypassing geo-restrictions and maintaining anonymity online.
