Why can your entire home use the Internet using just one public IP?

Why can your entire home use the Internet using just one public IP? 🤔

NAT explains it 👇

🔹 Static NAT — fixed mapping (1 private ↔ 1 public)
🔹 Dynamic NAT — pick from a pool of public IPs
🔹 PAT — many devices share 1 IP using ports (most common)

Why NAT matters:
✔ Saves IPv4 addresses
✔ Hides internal IPs
✔ Lets private networks talk to the Internet
