Azure VM 的动态专用 IP 地址的 TTL？
TTL of Dynamic Private IP Address for Azure VMs?
为基于 Azure 的 VM 分配给 NIC 的动态私有 IP 的生存时间是多少？
可以看到动态IP地址的说明here:
Once assigned, dynamic IP addresses are only released if a network
interface is deleted, assigned to a different subnet within the same
virtual network, or the allocation method is changed to static, and a
different IP address is specified. By default, Azure assigns the
previous dynamically assigned address as the static address when you
change the allocation method from dynamic to static.
也就是说，如果您不删除或更改虚拟机网络接口的配置，那么动态IP地址将作为静态IP地址使用。
