Good start. What about globally unique? Not immediately clear one can get uniqueness without some sort of registration. But the registration might be fairly painless. > My personal view on this is that there needs to be some ambiguity as > well, for two reasons: I don't follow what you mean by "ambiguous". > a) Ambiguous addresses would obviously be a smaller block which in turn > would be a lot easier to obtain from IANA; you know this part a lot > better than I do so I'd be happy to hear your views about this. > b) Ambiguous addresses are a guarantee that they will never be globally > routable because the block is too small. Well, there are no guarantees, but if there was a chunk of address space reserved for "globally unique, but no expectation that it will ever be routed on the public internet", and it came out of a well known prefix, I'd expect that enough ISPs would filter on them to keep them from being usefully routable in a global sense.
