Service Cluster IP range for Kubernetes: 10.254.0.0/16 (You can choose any IP range just make sure it does not overlap with any other IP range) 4. Kubernetes Service IP: 10.254.0.1 (First IP from service cluster IP range is always allocated to Kubernetes Service) 5. DNS service IP: 10.254.3.100 (You can use any IP from the service cluster IP range just make su...
