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?
