 The examples below use IPv4 addresses but you can also configure kubeadm, the kubelet and etcd
 to use IPv6 addresses. Dual-stack is supported by some Kubernetes options, but not by etcd. For more details
 on Kubernetes dual-stack support see [Dual-stack support with kubeadm](/docs/setup/production-environment/tools/kubeadm/dual-stack-support/).

 下面的例子使用 IPv4 地址，但是你也可以使用 IPv6 地址配置 kubeadm、kubelet 和 etcd。一些 Kubernetes 选项支持双协议栈，但是 etcd 不支持。
 关于 Kubernetes 双协议栈支持的更多细节，请参见 [kubeadm 的双栈支持](/zh-cn/docs/setup/production-environment/tools/kubeadm/dual-stack-support/)。
