It's been discussed. It was called something like "aggregation with
increasing scope." The basic idea works like "loose source routing."
The first address in the path is the anycast top-level waypoint for
the destination system, followed by additional waypoints until you
enter the final scope. The DNS for this returns a list of 32-bit
values as the address instead of a single 32-bit or single 128-bit
One of the nice features is how easily it expands and contracts. If
you need more addresses inside your system, you just add one level of
scope and presto, you have 4 billion more addresses to play with, no
registry fuss required.
