Many personal computers can establish LANs behind them, and/or can run
several internal virtual machines (what I call "host-rooted subnets").
Let's assume such a host is on a /64 link, with a /128 address.
What a depressing assumption.
Why not assume it's on a /64 link but has been assigned 16 /128 addresses?
The idea is that a typical default behavior consists in taking as IID
the modified EUI-64 that is derived from the unique MAC address
available on the link.
But, yes, other assumptions are possible. The CPE, and intermediate
routers if there are some, can indeed use prefix-delegation. This is
however, IMHO, not as typical and simple.
Prefix delegation, which has its own applicability scope, seems to me
somewhat opposed to that of SLAAC. More intermediates solutions seem
possible. SAM is thought to be a starting point for this, but I am
conscious that this still needs to be clarified.
