"Only"? Please. An obvious benefits of v4 over v6 is that it is deployed. Another benefit is the operational experience gained over the years running v4 infrastructures. NAT, despite being the spawn of the devil, at the very least leverages both of these advantages. More realistically, some might consider IPv4 address allocation policies as discouraging the growth of the Internet (I am not among them), but I remain unconvinced IPv6 address allocation policies will be significantly different in the aspects that cause people to be discouraged. Most, if not all, of the same people who are refused IPv4 address allocations will (or should if we expect not to re-create the swamp) be refused allocations of IPv6 addresses. Rgds, -drc
