* 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.

	// the characteristics of a NodeInternalIP. The IP it resolves to may or may not
	// be a listed NodeInternalIP address.
	NodeInternalDNS NodeAddressType = "InternalDNS"

	// NodeExternalDNS identifies a DNS name which resolves to an IP address which has
	// the characteristics of a NodeExternalIP. The IP it resolves to may or may not
	// be a listed NodeExternalIP address.

* 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))

NodeInternalIP).\n - `\"Hostname\"` identifies a name of the node. Although every node can be assumed to have a NodeAddress of this type, its exact syntax and semantics are not defined, and are not consistent between different clusters.\n - `\"InternalDNS\"` identifies a DNS name which resolves to an IP address which has the characteristics of a NodeInternalIP.
