Historically, the address blocks received from ARIN also meet between 3 and
12 months of need (i.e. used to connect customers) all in one contiguous block.
This means that many, many customers can be connected with only a small
number of routes injected in the global routing tables.  This hierarchy seems
to be important for Internet scaling, and address blocks transferred between
parties doesn't necessarily exhibit the same properties (unless they are just
as large and transferred predominantly to ISP's...)
