That's an option not reachable so far.

I don't know in your country but in France and EU for what I see so far, we are really really late on IPv6.

OVH in France does not offer IPv6 on Kubernetes cluster, and most home router does not have it enabled.

It would have been my first choice indeed. When we started this project a year ago we for sure decided to be dual stack, but we couldn't afford the limitation set by others on the lack of spread of IPv6.
