What is "more than rudimentary" support? AWS supports public IPv6 for virtual instances, all three support it for their load balancer products, and AWS supports it for a number of additional services (S3, CloudFront, WAF). Most of this support has been released within the last year, and I'm sure that this is work that's been in progress for a while and that improved support is coming. Cloud providers are ready for developers to build products accessible over IPv6. Are developers ready to build them? |

> Has anyone tried running IPv6 in AWS? It kinda seems like using it for containers is still very messy. IPs are assigned via DHCPv6 and you cannot actually turn off src/dest checking, so to assign public IPv6 address on each container, you would need to assign each IP address one by one on the interface via AWS API and use a hook in host's DHCPv6 client that adds the IPv6 address to NDP proxy (not 100% sure if this is required) and disables assigning it to interface. With this, you would get 10-30 IPv6 addresses per interface and with some additional hacks to use multiple interfaces you could possibly get 240 IPv6 addresses per instance on larger instances (or well, 16xlarge instances give 15*50)
Though admittedly even if there was a support for getting prefixes to instances, it would still take time for other things to get support for it (e.g. Kubernetes)
