Justin,

I'm not sure you're not confusing scope here.

Everybody and their sister accept smaller blocks from their customers; we're
all talking about the DFZ here, not customer routes that you aggregate.

Actually, we don't.

From our customers, the most we are accepting today is a /24 and a /48. This is for transit customers with their own AS and address space.

Of course, if it's a DIA customer, we can assign longer prefixes, but that is internal address space that belongs to us.

Mark.
