If most organizations use provider assigned address space instead of
/48 portable assignment, they are not necessarily gonna dump their
entry in the routing table, is that correct?
that is a big if, which has not held up well in actual measurement.
and, of course, there is the issue that de-aggregation seems to be
a major sport in asia/pac, see a lot of geoff's measurements.
So, it's not about placing a barrier to entry in the market, it's
placing a barrier to entry in the routing table.
those are the words we have been using for years while closing our ears
to the people screaming at the barriers.
