Re: Another IPV6 article which exposes issues with IPV6
You don't need a specific allocation for the IPv6 network. The IPv6-only host doesn't need to know about IPv4 at all.
NAT64 is usually combined with DNS64. An IPv6-only host will do a DNS request, the DNS resolver will see if the response only includes IPv4 addresses. If so, it rewrites the response to an IPv6 address that points at the gateway and encodes the IPv4 address. The gateway then has the smarts to spot this IPv6 packet is actually for an IPv4 host and translates it.
NAT works in both directions, you publish your service on a public IPv4 address and translate it to the IPv6 server sitting behind the gateway.
