You can still use a shorter hash of the Mac address. Collisions are very unlikely, and a quick ARP packet should detect them if they do happen.

- ale42 3y agoIt would rather be an ICMPv6 neighbor discovery packet or something like that, IPv6 doesn't use ARP.
- ta1243 3y agoCollisions are just as likely with the 48 bits as they are with the last 24 bits, as some OUI vendors reuse mac addresses. Using a mac address in the IP is terrible anyway from a privacy point of view, use a random IP in the subnet, send out a check to see if it's already used, if it is choose a new one. That check is already a feature of ipv6.
