What are the Public and Private IP addresses?

Question

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.

A private IP is assigned by your router, and is only addressable within the network (to put it simply). To go from private to public IP your router does NAT (Network Address Translation)
