How does that work with MAC address conflicts and clashes? I naively thought every MAC address had to be unique. | ||||||||

They must be unique in a LAN segment. And only the lower 3 bytes in a MAC are “unique” as the upper 3 are the vendor ID and relatively fixed. In practice people put fewer than 256 devices on networks (class C), so they have less than 1/65536 possibility of complete failure. And far less because they have a mix of OUIs. But yeah, if you put a few hundred or thousand security cameras or other device from a single vendor, all on the same network, conflicts are certainly possible. MAC conflicts are also a bit nasty to troubleshoot, and less obvious than IP conflicts. | ||||||||

There are like 50 trillion possible addresses, unlikely to clash in one network :) |
