In RIPE land, it's the ISP's decision what size to assign to end users
(/64.../48).  For HD ratio utilization, the RIPE NCC will count the number 
of assigned /56s, with a /48 assignment being counted as "256 /56".

RIPE policy doesn't answer the question about "residential BCP", though -
and that seems to coalesce to "residential = /56, business = /48" when
looking at the larger players.

The IETF formally left the address space distribution regime when they
delegated responsibility to ARIN.
