Re: Mac OS X 10.7, still no DHCPv6

Dual stack isn't always the best approach. For networks that pass a large amount of traffic to a relatively small number of destinations, NAT64/DNS64 on a native v6 platform might be a better migration approach. If 90% of your traffic is v6, it is probably less trouble to use NAT64/DNS64 to reach that 10% than it is to dual-stack.

the scenario i think of here is the enterprise which wishes not to use private space so deploys v6-only internally, and nat64 at the border to a dual-stack provider. randy
