Well that’s not really what I’m referring to. I’m talking about EUI-64, which was supposed to make life easier by giving everyone an IP addressed based on their MAC address. You wouldn’t need to worry about address collisions with such an address, as it would be globally unique.

But following up on it a little just now, it seems the idea is falling out of favour precisely due to the privacy issues I was fretting about. I assume that means DHCP or some similar scheme will come to dominate just as with IPv4? I’m not an IT guy so I don’t know what the current thinking is on this.
