Azure Container Networking Interface (CNI) now supports dynamic IP allocation and defining a different subnet for agent nodes and pods in Azure Kubernetes Service (AKS). This enables IPs to be allocated dynamically when a pod needs it, instead of pre-allocating a subset of IPs to each agent node. This reduces IP usage as compared to a static allocation. Dynamic IP allocation also allows customers to setup clusters that consume fewer IPs. It also allows you to segment incoming traffic from pods and nodes separately and add new subnets to increase the pod CIDR.
