Remember the subnet for Docker containers should at least have a size of `/80`.
This way an IPv6 address can end with the container's MAC address and you
prevent NDP neighbor cache invalidation issues in the Docker layer. So if you
have a `/76` for your whole environment use `/78` subnets for the hosts and
have a `/64` for your whole environment use `/76` subnets for the hosts and
`/80` for the containers. This way you can use 4096 hosts with 16 `/80` subnets
each.
