And not all global networks (needing unique numbering) connect to the
global "public" internet.

That's a good check, but not sufficient. When last we fixed an ASN
registration, the check showed that other ASN's we had were not seen
in that table. We just mentioned "they are used on another
inter-network" and passed.
Kinda like "belts and suspenders" but let's make sure the fly is shut too. ;)

Right...or maybe in a different universe.

This is why an inter-registry database inspection tool is needed.
The traditional one is WhoIs - which as Randy mentions is too vague
in content. (The WhoIs spec only says something about TCP to port
43...and nothing about the query/response formats.) A tool like IRIS
is on the shelf that could be a platform from which to build
Checking the global public internet tables is a good first step, but
that's not all that is needed. Such a step only gives credence to
uniqueness, but it doesn't guarantee it.

As with IPv6, the problem with the deployment of frictionless surfaces is
that they're not getting traction.
