對于Windows下ping指令相信大家已經再熟悉不過了，但是能把ping的功能發揮到最大的人卻并不是很多，當然我也并不是說我可以讓ping發揮最大的功能，我也只不過經常用ping這個工具，也總結了一些小經驗，現在和大家分享一下。

現在我就參照ping指令的輔助說明來給大家講我使用ping時會用到的技巧，ping只有在安裝了TCP/IP通訊協定以后才可以使用：

ping [-t] [-a] [-n count] [-l length] [-f] [-i ttl] [-v tos] [-r count] [-s count] [[-j computer-list] | [-k computer-list]] [-w timeout] destination-list Options: -t Ping the specified host until stopped.To see statistics and continue - type Control-Break;To stop - type Control-C. 不停的ping地方主機，直到你按下Control-C。 此功能?有什么特別的技巧，不過可以配合其他參數使用，將在下面提到。

-a Resolve addresses to hostnames. 解析電腦NetBios名。 例：C:＼>ping -a 192.168.1.21 Pinging www.startcn.net [192.168.1.21] with 32 bytes of data: Reply from 192.168.1.21: bytes=32 time<10ms TTL=254 Reply from 192.168.1.21: bytes=32 time<10ms TTL=254 Reply from 192.168.1.21: bytes=32 time<10ms TTL=254 Reply from 192.168.1.21: bytes=32 time<10ms TTL=254 Ping statistics for 192.168.1.21: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms 從上面就可以知道IP為192.168.1.21的電腦NetBios名為www.startcn.net。 -n count Number of echo requests to send. 發送count指定的Echo數據包數。 在默認情況下，一般都只發送四個數據包，通過這個命令可以自己定義發送的個數，對衡量網路速度很有幫助，比如我想測試發送50個數據包的返回的平均時間為多少，最快時間為多少，最慢時間為多少就可以通過以下?知： C:＼>ping -n 50 202.103.96.68 Pinging 202.103.96.68 with 32 bytes of data: Reply from 202.103.96.68: bytes=32 time=50ms TTL=241 Reply from 202.103.96.68: bytes=32 time=50ms TTL=241 Reply from 202.103.96.68: bytes=32 time=50ms TTL=241 Request timed out. ……………… Reply from 202.103.96.68: bytes=32 time=50ms TTL=241 Reply from 202.103.96.68: bytes=32 time=50ms TTL=241 Ping statistics for 202.103.96.68: Packets: Sent = 50, Received = 48, Lost = 2 (4% loss),Approximate round trip times in milli-seconds: Minimum = 40ms, Maximum = 51ms, Average = 46ms
