What is a VPN (virtual private network)?

TechnologyLesson on requestFree to read

Quick answer

A VPN, or virtual private network, creates a private, encrypted tunnel between your device and the internet. It hides your real location and scrambles your traffic, so others on the same network — and even your internet provider — can't easily see what you're doing online.

Key things to understand

  1. An encrypted tunnel between you and the internet.
  2. Hides your IP address and apparent location.
  3. Protects data on public Wi-Fi from snoopers.
  4. Used for privacy and to reach region-locked sites.

What does a VPN actually do?
It encrypts your internet traffic and routes it through a remote server, masking your location and shielding your data from others on the network.
Is using a VPN legal?
In most countries, including India, using a VPN is legal — though using one to commit a crime is not.
Does a VPN make me completely anonymous?
No. It greatly improves privacy, but the VPN provider can still see your traffic, so a trustworthy provider matters.
