推荐答案

没有保证的方式获取连接到您的本地段的所有设备的地址。机器可能被防火墙和删除重新请求，或者在检查机器未配置为访问的不同子网中具有IP地址。

There is no guaranteed way to get the addresses of all devices connected to your local segment. Machines may be firewalled and dropping requets, or have IP addresses in different subnets that the checking machine isn;t configured to access.

您可以在子网上找到所有设备通过向本地子网上的每个IP地址发送ping请求（使用IP Helper库中的 ICMPSendEcho（））并检查响应来响应ping。

You can find all devices on the subnet that respond to a ping by sending a ping request (using ICMPSendEcho() in the IP Helper library) to every IP address on the local subnet and check for responses.
