Today, ISPs experience a cost advantage when they limit the number of addresses or provide only dynamic addresses. That cost advantage is a result of scarcity, and will therefore not exist in IPv6. If there is no cost advantage, there can be no differentiation. We aren't here to provide methods of differentiation; we're here to ensure a level playing field. But if there is such a factor in IPv6, it will likely be the cost advantage of route aggregation, undistorted by the effect of scarcity. Remember that since CIDR arrived, we have been constantly balancing scarcity against aggregation, and with IPv6 that balancing act largely goes away.
