Can you elaborate on why /56 is "bad advice" and if you're saying it only
for this case or if you're saying assignment of /56 to any customers is a
bad idea? Dealing with a data center where customer machines typically
get by today with a /29 of IPv4, is a /56 really not enough for their
forseeable future?
I realize our /32 could support more customers than we're likely to fit in
the data center at /48 per customer, but is that enough of a reason to
assign 65k /64 subnets to each customer machine?
