Let me past something that I posted to Calico Slack about a week ago:

> 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)

You have to admit you are pushing it to the limit there. Most people just want one IPv6 address per VM and that is working.

Just because most people want a broken setup, doesn't make it any less broken.
