At my previous job, we had a whole infrastructure which was IPv6 only (a dozen k8s clusters). Everything worked really well (though I had to make some PRs on projects to make them v6-compatible). However, we still needed a NAT64/DNS64 infrastructure because some external services were still v4-only (docker registry for example).
