Well...I do not know the right answer...In some scenarios it does make
sense (for example I'd prefer my laptop and my desktop
to do that), while for mobile devices it might not be the best way to
operate (why DNA was created in the first place?).
Maybe DNA assumptions need to be changed to 'the combination of the
link-layer address, the link-local IPv6 address and the list of PIOs
is unique across links'?
