Don't confuse allocations with assignments. A hosting provider would
need an allocation, from which they can make assignments to their
customers/end users. Their own enterprise networks could be considered a
"customer" too, by making an assignment to themselves from their PA

If that is not desirable, for some reason or another, the provider could
instead obtain a direct assignment (PI) from the NCC. They would not
have a second /32 allocation, but they would instead have a separate /48
assignment for their enterprise infrastructure. There would therefore be
no need to deaggregate the /32.
