-   
-#. 由于 QingCloud 不会为使用默认网络创建的虚拟主机自动分配公网IP地址，所以我们需要手动申请，并添加到虚拟主机。如图9点击导航栏左侧的 **“网络与CDN”** 按钮。
+#. Since QingCloud does not automatically assign a public IP address to a
+   virtual host created using the default network, we need to manually apply
+   and add it to the virtual host. Click the :guilabel:`网络与CDN` (Network and
