ping的基本用法想必大家都会，可知不值到有关ping命令的高级用法呢？如下面的：

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地方主机，直到你按下Control-C。

此功能没有什么特别的技巧，不过可以配合其他参数使用，将在下面提到。
-a Resolve addresses to hostnames.
解析计算机NetBios名。
示例：C:＼>ping -a 192.168.1.21
