What's the Difference Between Public IP vs Private IP Range? Need Clarification! or Public IP vs Priv

If everything used public IPs, we’d run out *fast*. IPv4 only has ~4.3 billion addresses, and there are way more devices than that.

Private ip ranges (10.x.x.x, 172.16.x.x, 192.168.x.x) let networks reuse the same IPs internally. NAT bridges the gap by mapping multiple private IPs to one public IP.

Tools like Wireshark can help visualize the traffic if you wanna dive deeper.
