In the context of Kubernetes, each {{< glossary_tooltip text="Node" term_id="node" >}} is assigned a range of IP addresses through the start address and a subnet mask using CIDR. This allows Nodes to assign each {{< glossary_tooltip text="Pod" term_id="pod" >}} a unique IP address. Although originally a concept for IPv4, CIDR has also been expanded to include IPv6.
