 这个模型不仅不复杂，而且还和 Kubernetes 的实现廉价的从虚拟机向容器迁移的初衷相兼容，
 如果你的工作开始是在虚拟机中运行的，你的虚拟机有一个 IP ，
 这样就可以和其他的虚拟机进行通信，这是基本相同的模型。
 
-Kubernetes 的 IP 地址存在于 `Pod` 范围内 - 容器分享它们的网络命名空间 - 包括它们的 IP 地址。
+Kubernetes 的 IP 地址存在于 `Pod` 范围内 - 容器共享它们的网络命名空间 - 包括它们的 IP 地址和 MAC 地址。
 这就意味着 `Pod` 内的容器都可以通过 `localhost` 到达各个端口。
 这也意味着 `Pod` 内的容器都需要相互协调端口的使用，但是这和虚拟机中的进程似乎没有什么不同，
 这也被称为“一个 Pod 一个 IP” 模型。
