Why have we not run out of ip addresses?

Question

With the massive growth in internet devices, shouldn’t we have used up all possible ipv4 numbers?

Answer 1

We did, sort of. We have way more devices than ipv4 addresses, but a lot of them are using the same address and hiding behind a local network. For most broadband setups, your entire WiFi network is only consuming one public IP and it’s using a whole bunch of local IPs behind your router.
