But that's the fatal flaw of autoconfiguration. "Hosts chosing the
low-order bits" works great until either A) one of those hosts wants a
semi-permanent name lodged in a DNS server and the IT guy wants to
semi-permanently assign an IP address to it without having to touch the
host configuration or B) the RIAA/MPAA/FBI/etc. comes and asks to see
the logs which show which user on the subnet had a particular address
and then goes to the local court and claims that you're using this
newfangled protocol so as to avoid making information available that has
"always" been available before.
If *both* of these problems were fixed as well as DHCP fixes them for
IPv4, there'd be a whole lot more support for letting the hosts choose
their low-order bits.
