如何用ping命令查询域名
在计算机网络中,ping命令是一种常用的网络诊断工具,可以测试本地计算机和远程计算机之间的连接是否正常。通过ping命令还可以查询域名的IP地址。
使用ping命令
在Windows操作系统中,打开命令提示符窗口(Win+R打开“运行”对话框,输入cmd并回车),输入ping命令,后面跟上要查询的域名即可。例如:
ping www.baidu.com
执行以上命令后,系统会向百度服务器发送数据包,并显示发送数据包的数量、接收到响应的数据包的数量、数据包传输的时间等信息。最后,系统会显示域名的IP地址。例如:
Pinging www.a.shifen.com [14.215.177.38] with 32 bytes of data:
Reply from 14.215.177.38: bytes=32 time=15ms TTL=54
Reply from 14.215.177.38: bytes=32 time=14ms TTL=54
Reply from 14.215.177.38: bytes=32 time=14ms TTL=54
Reply from 14.215.177.38: bytes=32 time=14ms TTL=54
Ping statistics for 14.215.177.38:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 14ms, Maximum = 15ms, Average = 14ms
使用ping命令查询特定IP地址的域名
有时候,我们需要查询一个IP地址对应的域名。这时候,可以使用ping命令的-a参数。例如:
ping -a 14.215.177.38
执行以上命令后,系统会显示IP地址所对应的域名。例如:
Pinging www.a.shifen.com [14.215.177.38] with 32 bytes of data:
Reply from 14.215.177.38: bytes=32 time=14ms TTL=54
Reply from 14.215.177.38: bytes=32 time=14ms TTL=54
Reply from 14.215.177.38: bytes=32 time=14ms TTL=54
Reply from 14.215.177.38: bytes=32 time=14ms TTL=54
Ping statistics for 14.215.177.38:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 14ms, Maximum = 14ms, Average = 14ms
Ping 的 Ping 统计信息:
数据包: 已发送 = 4,已接收 = 4,丢失 = 0 (0% 丢失),
往返行程的估计时间(以毫秒为单位):
最短 = 14ms,最长 = 14ms,平均 = 14ms
Approximate translation in English:
Ping statistics for 14.215.177.38:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 14ms, Maximum = 14ms, Average = 14ms
总结
通过ping命令可以查询域名的IP地址,也可以查询IP地址所对应的域名。这对于网络管理员来说是非常有用的工具。
