My understanding of the discussion with Thomas is that one could
rather use the SDNA stuff as a possible source for the Network_ID
parameter. That' be great. (I proposed some text to Thomas, and I'm
waiting for his response).

Regarding use of DNA as proposed in the suggested paragraph above, I
have no issues with it, although it seems orthogonal and out of scope
*here*. -- i.e., such note might make more sense for the other
document that has just been adopted. This one is about what to do when
you have already "decided" that you cannot reuse the
previously-assigned address.

Thoughts?
