How a VPN Works (Step by Step)

What a VPN Does (in short)

A VPN:

• Hides your real IP address
• Encrypts your internet data
• Creates a secure tunnel between your device and the internet

How a VPN Works (Step by Step)

1️⃣ You connect to a VPN app

You open a VPN app on your phone or computer and click Connect.

2️⃣ Encrypted tunnel is created 🔐

The VPN creates a secure, encrypted tunnel between:

• Your device
• The VPN server

Anyone watching your traffic (Wi-Fi owner, ISP, hackers) can’t read your data.

3️⃣ Your IP address is hidden 🌍

Instead of websites seeing your real IP, they see:

• The VPN server’s IP address

Example:

pgsql

Copy code

Before VPN → IP: 103.xxx.xxx.xxx (your real location)

After VPN → IP: 45.xxx.xxx.xxx (VPN location)

4️⃣ Your data travels safely

Your internet traffic goes:

pgsql

Copy code

Your device → Encrypted tunnel → VPN server → Website

And back the same way.
