/hold This is a preview of the idea to adjust MAPA to react based on the infra status Important: We have not finalized on which direction to go yet (i.e. auto react or explicit MAPA machine field) 👀 |

I am OK with this approach where we look at Infra CR which I think is what you are calling "auto react" vs adding a new field to MAPA. |

Hi @sunzhaohua2, as the installer dualstack support is in progress, I can verify this PR myself via local testing (for dualstack) and via presubmit (for regression). Later on, Yunfei can test the full feature together. |

/verified by @tthvo Machines are assigned primary IPv6 address as expected. |

Description
For dual-stack IPv6-primary clusters, instances must have a primary IPv6 address on their primary ENI to registery with the IPv6 Target Groups of API and Ingress load balancers. See AWS docs
Notes
This assumes that the containing subnet is dual-stack (has both IPv4 and IPv6 CIDRs) since we are requesting an IPv6 address for the instance. The subnets, created by installer/capa, will be dual-stack and will auto-assign an IPv6 address on launch.
