Port numbers are like extensions to your IP address. For example, your computer’s IP address is 53.125.105.18, while the file transfer protocol (FTP) port number is 20. Thus, the IP for an open FTP port would be 12.345.678.90:20. By seeing this address, the server will “understand” your request.

What is a VPN and how does it work?
A virtual private network (VPN) encrypts online traffic and enhances privacy by changing the IP address and virtual location. It does so by routing all your internet traffic through a remote server. NordVPN offers over 5,200+ servers in 60 countries. It’s especially important to have VPN protection when you connect to public Wi-Fi. Public hotspots are inherently unsafe — cybercriminals can easily compromise them or set up fake hotspots to lure unsuspecting victims. You should always use NordVPN before connecting to public Wi-Fi.
NordVPN is available on every major platform. You can use NordVPN on your laptop (Windows, macOS apps) or download it on your phone (Android, iOS apps). There’s also a NordVPN app for Android TV and Linux, while the lightweight extensions for Chrome and Firefox can secure your browsing in an instant.
