What's the Real Difference Between Private vs Public IP Addresses? or Private vs Public IP Addresses:

Okay, imagine private vs public ip addresses like a post office:

- Public IP = the PO Box (unique, mail comes here).
- Private IP = the sorting room (workers handle mail internally).

Your router’s NAT is the mail sorter—translating private to public so your devices can share one "PO Box."

And nah, it’s not easier with all public IPs. We’d run out faster than toilet paper in 2020.
