<p>I have configured Kubernetes with 4 node and the IP addresses are assigned with some ranges</p>

<ul>
<li><p>node1: 172.25.10.4 - 172.25.10.34</p></li>
<li><p>node2: 172.25.10.35 - 172.25.10.65</p></li>
<li><p>node3: 172.25.10.66 - 172.25.10.96</p></li>
<li><p>node4:172.25.10.97 - 172.25.10.127</p></li>
</ul>

<p>But in the VM Scale Set Instance each nodes are assigned with the static IP. </p>

<p>Will the private IP change at any instance?
Why this range of IPs are assigned for a single node?</p>

<p>No, they won't change at any point in time (well, when you upgrade your cluster you nodes will get recreated, so these IP addresses will get shuffled a bit). They are assigned because pods are getting assigned those IP addresses from the Virtual Network. By default 30 pods can run on a single host, so 30 + 1 (host IP address) IP addresses are assigned to each host.</p>

<p>But you shouldn't really depend on those IP addresses at all.</p>
