I do not know. There is a problem when all operators deliver only /64s. The problem is for mobile hotspots, vehicular networks, and probably others, who need more than just a single /64. In implementation, DHCPv6-PD has itself some problems on smartphones, regardless of using /64s or other plens. That DHCPv6 problem is at the modem manufacturers who block DHCPv6. A telecom operator might or rather might not be able to work towards solving it at the modem manufacturer. A regulator might work with mobile telecom operator towards assigning more than a single /64 to end users. > There is too big a power differential between the cellular user that > want to be able to have multiple subnets and the telcos for free > market economics to work. I can see such differential as between large and small dented wheels, but I dont understand quite what do you mean? Do you think there are too few users in need of multiple subnets for make a market uptake? For my side I can cite figures of the autonomous connected automobiles market poised to grow to billions of dollars capitalization in the next few years.
