When adding a third host you would add a route for the subnet 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.
