Why doesn’t every computer have a hardware based static ipv32 address, along with a private key to prove it is the sole owner of the address?

    Yes, but no. The public IP is that of the router, which NATs packets to each host, each of which must have a unique private IP. The public IP does not reference or identity hosts behind the router. And that’s not how HA works. Only one host is assigned the active IP at one time.

      So computers can share IP’s then right? By your example they are sharing their public IP. From the perspective of the server you are connecting to, all the machines on your LAN have the same IP. Same way multiple physical phones can be connected to a single landline, all those phones share the same number.

      When you do call routing with a PBX each phone has an unique extension, equivalent to the private IP of each host.

      Oh, and there’s also anycast, which is literally multiple active devices sharing an IP.
