Under the current policy, if MERIT should only have to demonstrate
38,000 downstream customers (students) to qualify for a /28,
not counting downstream customers of universities that have
their own allocation.

Under the current policy, each university should easially qualify for
their own /32.

For dorm rooms, universities should be able to assign students
anywhere from nothing (let them use university "assigned" space) or
their own /48.
