windows平台上

使用for命令，可以查询for命令的用法,直接输入 for /?

C:\>for /l %i in (1,1,25) do ping -n 1  -w 60 147.2.147.%i  | find "Reply" >>d:\ping.log

备注：%i in (1,1,255) ——是遍历主机位从1 ~ 255的所有IP
     -n——ping 的次数
     -w ——timeout时常
     192.168.0.%i ——遍历IP 自192.168.0.1 ~ 192.168.0.255的所有IP
     | bat ——管道，将前面的结果通过管道输入给后面的命令
     >> bat——重定向，将结果写进d:\pingall.log这个文件           

C:\Documents and Settings\Administrator>type d:\ping.log

Linux平台上   
ping一个网段，看回显，用nmap

nmap -sP -n 172.27.205.0/24
