There's a nice feature on Solaris for tokenised IDs such that you can
specificy manually the host part of an address, e.g. ::53 on a DNS server,
and the full address is formed from the RA information.   A colleague
did a similar implementation for Linux.    So an address can in principle
be partially manual :)

And DHCP can assign temporary addresses.

Alain sums it up best I think - you can only make a best guess.
