以下为官方定义原文: ping uses the icmp protocol's mandatory echo_request datagram to elicit an icmp echo_response from a host or gateway. I need to find its location i'm using the app find my device but i don't know exactly what to be listening for Ping 只能当辅助网络,不能只根据这个而定。 如目标 ip主机 本身禁止了ping的,ping不通是正常的;如本地网络限制了ping的,更换另个网络环境下可能又能ping通状态。 网站可以打开,但登录.
