Excellent commentary!

For the readers to consider in thinking about your comments:
The aviation industry will be developing at least three independent IP
networks serving each commercial aircraft flying the world.  These
networks will span the entire globe!  (We have several airlines that
have aircraft that literally complete a circle of the globe every few

The air traffic control network will be closed as it is today.  But the
addressing still ideally should come from a single block of addresses
(sub-addressed between aircraft and ground system).  And these addresses
will need to be pooled, distributed, and managed under the rules of the
International Civil Aviation Organization.  In ICAO's case, they will
need the allocation years ahead of the first actual use as they will
have to make their allocations from that space to the airlines and
governments around the world.

The airline networks, for their business communications with their
fleets, will also need to almost certainly use a global network design.

As will the onboard networks dedicated to serving the passengers for
both Internet and live video content to the seat back.

I think you will see the same requirements from the maritime and several
other industries.

Industry and business needs the some type of consideration here.

Take care

PS: Especially "critical infrastructure"!  Next time you are at home and
the snow is really deep outside and the wind blowing or it is really hot
and the air conditioner is going full tilt, ask yourself if you would
like for your power company to be planning switching ISP's that day and
re-addressing all their SCADA systems across three or four states?

And can you imagine when would be a good time for an airline (even a
small one) to switch ISP's without potentially disrupting your travel

Or consider any other critical infrastructure that you have to deal with
daily and remember critical infrastructure includes small businesses;
hospitals, clinics, banks, local fuel distributor, refineries, gas
company, etc.  When would be a convenient time for them to change ISP's
and switch addresses so no one was impacted?
