如何搜索到某网段的所有PC的IP?

[Kin_CIOM]

谢谢

[铖邑]

可以PING一下该网段的广播地址试试看？

[duduwolf]

最简单的办法，把该网段的IP一个一个进行PING操作，如果PINT通了记入LIST列表

[godmayknow]

我也在关注这个问题。
xpdavis的办法不可行。
duduwolf的办法比较累，要是为A类网址...嘿嘿。没准还有双网卡。

没什么好办法 ping很实在啊
速度也很快

[Kin_CIOM]

帮帮忙啊!

[nanhui]

也许真的要一个一个的PING了

netbios探测，很快:)

[gycxy]

发广播包,或对每个ip做一次连接测试.
但若有工具,那就直接办得多了,不用你费心了,

肯定是用ping的方法最好,我做过好几个这样的程序,用多线程,速度很快,我试过从192.168.131.1到192.168.254.254还不到一分钟,不要说一个网段了

netbios探测就一个线程，探测250个主机，最多10秒~

有没有代码让我学习一下啊?
