ARCnet is interesting. Deterministic performance, robustness/automatic ACKs, cables up to 2000 feet, still used in industrial settings. Biggest downsides seem to be lower speed and the limit of 255 nodes per LAN, but this addressing works better than Ethernet for IPv4 since the lower 8 bits of the IP address can be the LAN address, eliminating the need for complicated ARP exchanges. https://en.wikipedia.org/wiki/ARCNET https://en.wikipedia.org/wiki/ARCNET
