<p>Why there are two IP address classes in my Kubernetes cluster?</p>

<pre><code>kubectl describe svc cara

<p>after master installation I did:</p>

<pre><code>kubeadm init --v=0 --pod-network-cidr=192.167.0.0/16
kubectl apply --v=0 -f https://docs.projectcalico.org/v3.6/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml
</code></pre>

<p>I expect one range of IP addresses in my cluster network. Am I misunderstand something?</p>

<p>There are two main CIDRs in Kubernetes cluster - pod network and service network. It seems that your cluster has pod network 192.168.0.0/16 and service network 10.0.0.0/8.</p>
