打开命令行
1.在菜单栏中搜索命令行
2.在文件管理器的Path栏输入cmd，则在当前目录打开命令行
3.Windows+R，输入cmd，回车
ping(网络诊断工具)
ping是Windows、Unix和Linux系统下的一个命令
ping也属于一个通信协议，是TCP/IP协议的一部分
利用“ping”命令可以检查网络是否连通，可以很好地帮助我们分析和判定网络故障,用来作为可用性的检查
应用格式：ping空格IP地址 或者 ping空格域名
举例
C:\Users\xxx>ping Pinging [123.125.115.110] with 32 bytes of data:Request timed out.Reply from 123.125.115.110: bytes=32 time=52ms TTL=49Reply from 123.125.115.110: bytes=32 time=51ms TTL=49Reply from 123.125.115.110: bytes=32 time=52ms TTL=49Ping statistics for 123.125.115.110:Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),Approximate round trip times in milli-seconds:Minimum = 51ms, Maximum = 52ms, Average = 51msC:\Users\xxx>ping 123.125.115.110Pinging 123.125.115.110 with 32 bytes of data:Reply from 123.125.115.110: bytes=32 time=51ms TTL=49Reply from 123.125.115.110: bytes=32 time=51ms TTL=49Request timed out.Reply from 123.125.115.110: bytes=32 time=51ms TTL=49Ping statistics for 123.125.115.110:Packets: Sent = 4, Received = 3, Lost = 1 (25% loss),Approximate round trip times in milli-seconds:Minimum = 51ms, Maximum = 51ms, Average = 51ms
原理：利用网络上机器IP地址的唯一性，给目标IP地址发送一个数据包，再要求对方返回一个同样大小的数据包来确定两台网络机器是否连接相通，时延是多少
ipconfig(查看本机ip)
