How can I find what IP block is used by the api-service (or whatever other component is responsible) to dole out the service IPs, from a live cluster?
We use a self managed Kubernetes cluster deployed on AWS using Terraform. The networking is managed by Calico. However from what I have read it seems like Calico is only responsible for the pod and container IPs.
You can run below command, and in the output you will find your cluster ip range like --service-cluster-ip-range=x.x.x.x/x
kubectl cluster-info dump | grep --color service-cluster-ip-range
