title: IP usage in Kubernetes cluster
body: <p>I have an aks cluster with a single nodepool with azure cni network plugin and a subnet of /21 around 2000 ip's dedicated for this single nodepool. This nodepool is configured with 3 availability zones.</p>
  <p>Consider I have another cluster with a single nodepool with the configuration same as above but for the nodepool availability zone is set to none.</p>
  <p>Workloads are the same in both the nodepools. but will the nodepool deployed in 3 availability zones consume more ip's compared to the one deployed in the availability zone set to None</p>
