 With Azure CNI Overlay, the cluster nodes are deployed into an Azure Virtual Network (VNet) subnet, whereas pods are assigned IP addresses from a private CIDR logically different from the VNet hosting the nodes. Pod and node traffic within the cluster use an overlay network, and Network Address Translation (using the node's IP address) is used to reach resources outside the cluster. This solution saves a significant amount of VNet IP addresses and enables you to seamlessly scale your cluster to very large sizes. An added advantage is that the private CIDR can be reused in different AKS clusters, truly extending the IP space available for containerized applications in AKS.

 ## Overview of overlay networking
 
 In overlay networking, only the Kubernetes cluster nodes are assigned IPs from a subnet. Pods receive IPs from a private CIDR that is provided at the time of cluster creation. Each node is assigned a `/24` address space carved out from the same CIDR. Additional nodes that are created when you scale out a cluster automatically receive `/24` address spaces from the same CIDR. Azure CNI assigns IPs to pods from this `/24` space.
