Yes, I use IPv6 in production, alongside IPv4 (dual-stack). I've got an IPv6 only EKS cluster that has IPv4 on the local instance that NAT's any IPv4 outgoing connections, but the entire cluster and all communications inside the cluster/between pods is IPv6 only. IPv6 stand-alone without IPv4 dual stack is not yet an option, but it is getting closer. If you can mirror content and deploy from your mirrors it is entirely possible to do everything over IPv6 alone. About 30% of my production traffic is IPv6, referring to outside traffic coming in to the systems. Internally almost 90% of the traffic is IPv6 due to the k8s cluster being IPv6 only, and preferring that over IPv4. Interestingly enough at home on my home connection about 60% of my traffic is IPv6, which has been increasing steadily over the years as other companies have started bringing on-line IPv6 for their services.
