Yo, no dumb questions here! Private ip address vs public is confusing at first.
Public IP = your house’s street address. Everyone needs it to find you.
Private IP = your room number inside the house. Only your family (local network) cares.
Why not all public? Cuz IPv4 only has like 4 billion addresses, and there are WAY more devices. NAT (Network Address Translation) is the magic that lets your router share one public IP with all your private IP devices.
If you wanna nerd out, try Wireshark to see how traffic flows.
