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.

在 Kubernetes 的上下文中，每个{{< glossary_tooltip text="节点" term_id="node" >}}
|
||
以 CIDR 形式（含起始地址和子网掩码）获得一个 IP 地址段，
|
||
从而能够为每个 {{< glossary_tooltip text="Pod" term_id="pod" >}} 分配一个独一无二的 IP 地址。
|
||
虽然其概念最初源自 IPv4，CIDR 已经被扩展为涵盖 IPv6。
