That's quite a "medium-scale".

Is there a single entity in the world that controls 1,000 networks and

Well, sure, MCI is a single company that owns that many networks and
possibly network devices, but are you saying there's a single group of
people within MCI who are tasked with mapping, down to the host level,
across their entire network? It would seem reasonable to me that there is
some hierarchy involved...European division deals with its network, etc.

I am a network engineer for a cable ISP.  We have over 50,000 cable
modems and around 65,000 customer devices.  We only have 200-250
networks, but well over 100,000 ip devices.

What would be the value of mapping all those CPEs? Not that there isn't
one, I just don't know what it is.
