Azure AKS advanced Networking Design

Kubernetes cluster is created under Virtual Network k8s-vnet 10.0.0.0/8 (but it is limited to 65,536 configured IP addresses)

Under this Vnet we need to create a new Subnet named k8s-nodes-subnet with CIDR 10.10.0.0/16. This subnet is used by K8s nodes and Pods, so plan the sizing accordingly

Service Subnet 10.20.0.0/16. This IP ranges are used by the services in Kubernetes. This subnet should not conflict with the Nodes Subnet or Docker Bridge CIDR (Default 172.17.0.0/16)
