Public IP vs private IP is all about scope.
Public: The world sees it. Needed for servers, websites, etc.
Private: Only your local network cares. Used for your phone, smart fridge, etc.
Why not all public? IPv4 is limited (we’re running out!), and NAT (Network Address Translation) saves the day by letting multiple devices share one public IP.
Safety? Private IPs aren’t directly exposed, so hackers can’t target them as easily.
Tool tip: [Advanced IP Scanner](https://www.advanced-ip-scanner.com/) shows all private IPs on your network.
