Alberto,
The u bit in the current IID definition indicates whether or not the
IID can be considered globally unique. The zero value (implying *not*
globally unique) is used not only for randomly-generated ("privacy")
IIDs but also for manually-assigned IIDs, and IIDs assigned via DHCP
that are not derived from the node's IEEE-802 or EUI-64 address. In
other words, u=0 does *not* mean randomly generated; it means not-
globally-unique.
