One of the arguments put forward by those who prefer dhcp6 was that the
dhcp6 server could do that for any leases.  Just like for dhcp4.

For SLAAC, something based on mdns might do?  Ie, a multicast address
where a box can announce that it just joined the lan at a specified v6.

That also might be reasonable for privacy addresses.
