I’ve been diving into the public and private IP addresses, as I could understand public IP addresses are assigned by Internet Service Providers, but I couldn’t understand how and by whom are private IP addresses assigned. I couldn’t understand as well what’s the purpose of private IP addresses.
Any help is appreciated. Thank you for helping me out.

Your internet service provider (isp) assigns you a ip address. Your router uses that IP address to talk to the outside world. But your internal network will have multiple devices and every one of those devices will also need a ip address. So your routers assigns them a IP. Your router does all the conversions from internal to external and opposite.
