By design, AUTOIP-assigned addresses must not be deterministic.
If you're assuming the opposite, you'll have serious troubles as soon as
you'll connect your device to something more than your PC.
This is not true. It must handle conflicts, as you say, but the RFC actually
encourages using the same IP address on every power up.
You're right. The non-deterministic part is that at the next power on
the old address might be not available anymore or, as in Alex's case,
generate conflicts for some reason. In fact the RFC (section 2.1) states
that hosts should use the previously recorded address "as their *first
candidate* when probing".
I know it's exactly what you had in mind, I just wanted to clarify for
unexperienced users who might be tuned on this discussion.
