### The ungleich k8s cluster
The Kubernetes control plane access is available via IPv6 and
IPv4. All pods are running in a dedicated /64 IPv6 network.
Service IPs are IPv6 only and are located in a second /64 IPv6 network.
The cluster does not support type=LoadBalancer, because it is not
necessary in IPv6 only environments. ClusterIPs are already by default
world reachable.
IPv4 reachablity can be configured in two ways:
* Via our IPv4-to-IPv6 proxy (http, https based)
* Via a dedicated IPv4 address
The current stack uses Calico as the CNI.
