How would this work for a hypothetical example:

   Entity X has four distinct physical locations:
     Locations A and B are interconnected and share upstream providers.

     Locations C and D are each far away from the others, not
     interconnected, and may have distinct sets of upstream providers.

What would the assignment(s) for these look like?
More to the point, if a single /44 is assigned, is the expectation
that longer prefixes announced from the various locations would
be routable?
