现在我就参照ping指令的辅助说明来给大家讲我使用ping时会用到的技巧，ping只有在安装了TCP/IP通讯协议以后才可以使用：
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地方主机，直到你按下Control-C。
此功能?有什么特别的技巧，不过可以配合其它参数使用，将在下面提到。
-a Resolve addresses to hostnames.
解析计算机NetBios名。
例：C:＼>ping -a 192.168.1.21
