* Nodes can now report two additional address types in their status: InternalDNS
  and ExternalDNS. The apiserver can use --kubelet-preferred-address-types to
  give priority to the type of address it uses to reach nodes.

* You can now receive node DNS info with the `--node-ip` flag, which adds `ExternalDNS`, `InternalDNS`, and `ExternalIP` to kubelet's output. ([#63170](https://github.com/kubernetes/kubernetes/pull/63170), [@micahhausler](https://github.com/micahhausler))
