200 might be optimistic, agreed. I think 100 is pretty well assured absent
something much more profligate than current policies.

Technically, we’ve run one, we’re running a second one now, and yeah,
hopefully lessons learned can play a part.

Of course this also ignores the third transition which included a numbering
transition as enterprises went from running everything else (x.25, vines,
IPX, DECNET, AppleTalk, etc.) to IP.
