title: How to find out what podcidr is assigned to each node by calico CNI in kubernetes
body: <p>Is there any direct command to fetch the podcidr assigned to each node when using calico CNI.</p>
  <p>I am looking for exact network and netmask assigned to each node. I am not able to fetch it from <code>kubectl get nodes</code> neither via <code>podCIDR value</code> nor via <code>projectcalico.org/IPv4VXLANTunnelAddr</code> annotation. Also looks like the annotation will also differ based on VXLAN or IPIP tunnel used by calico.</p>
  <p>Tried to fetch via podCIDR key from nodes. Got the following output. Which wasn't the network assigned to the nodes.</p>
  <pre><code>kubectl get nodes -oyaml | grep -i podcidr -B 1
    spec:
      podCIDR: 192.168.0.0/24
      podCIDRs:
  --
    spec:
      podCIDR: 192.168.2.0/24
      podCIDRs:
  </code></pre>
  <p>Tried to fetch it via calico annotation. Was able to find the network but the netmask was missing.</p>
  <pre><code>kubectl get nodes -oyaml | grep -i ipv4vxlan
        projectcalico.org/IPv4VXLANTunnelAddr: 192.168.33.64
        projectcalico.org/IPv4VXLANTunnelAddr: 192.168.253.192
  </code></pre>
  <p>Tried to fetch it via calico pod. Found the exact network and netmask i.e <strong>192.168.33.64/26</strong> from the calico log.</p>
  <pre><code>kubectl logs calico-node-h2s9w   -n calico-system | grep cidr
  2020-12-14 06:54:50.783 [INFO][18] tunnel-ip-allocator/ipam.go 140:
  Attempting to load block cidr=192.168.33.64/26 host=&quot;calico-master&quot;
  
  </code></pre>
  <p>But i want to avoid looking at logs of calico pod on each node.
  Is there a better way to find the podcidr assigned to each node via a single command.</p>
