Re: Another IPV6 article which exposes issues with IPV6
What more do you want?
As I understand it, NAT64 provides a means for a host with an IPv6 stack to communicate with legacy IPv4-only hosts by means of a gateway. I gave up trying to pin down the shifting sands of IPv6 migration some time ago, so please correct me if any of the following is untrue regarding NAT64.
1/ it needs a specific form of address allocation for the local IPv6 network, the host needs to "know" when to embed IPv4 addresses in IPv6 packets and the gateway has to "know" what to do with them so it effectively adds a third mode of operation (IPv4, IPv6 and IPv4 in IPv6).
2/ It does nothing for the problem of IPv4-only hosts (either legacy systems or system sitting behind an IPv4 ISP) that want to communicate with IPv6-only systems, which would seem potentially to be a significantly greater number.
