 Regarding DNS, with both kubenet and Azure CNI plugins DNS are offered by CoreDNS, a deployment running in AKS with its own autoscaler. For more information on CoreDNS on Kubernetes, see [Customizing DNS Service](https://kubernetes.io/docs/tasks/administer-cluster/dns-custom-nameservers/). CoreDNS by default is configured to forward unknown domains to the DNS functionality of the Azure Virtual Network where the AKS cluster is deployed. Hence, Azure DNS and Private Zones will work for pods running in AKS.
