Yo, your analogy is spot on! Public ip address vs private ip address is basically about scale and security.
Public ips are unique worldwide—like your social security number. But private ips? They’re reusable behind your router. That’s why your neighbor might also have a device with 192.168.1.5, but it won’t clash because they’re in separate networks.
And nah, we can’t use public ips for everything ‘cause there’s only ~4 billion IPv4 addresses (and billions of devices). NAT (Network Address Translation) saves the day by letting multiple devices share one public ip.
Check out tools like Wireshark if you wanna dig deeper into how traffic moves between public and private ips.
