<p>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. </p>

<p>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. </p>

<p>You can run below command, and in the output you will find your cluster ip range like <code>--service-cluster-ip-range=x.x.x.x/x</code></p>

<pre><code>kubectl cluster-info dump  | grep --color service-cluster-ip-range
</code></pre>
