更换IP地址作弊的朋友注意了,ASP编写的代码都可以获取网卡的MAC地址,更不用说Google如何来获取MAC地址,不管你IP地址如何变,MAC地址是不变的,除非你不停的换网卡,所以同一台机子上更换IP地址作弊行不通,也不要冒险去作弊。
以下是ASP获得网卡的MAC地址代码,供大家有兴趣研究

更换IP作弊的方式似乎是个网民都知道行不通的。

有沒有php的?

担心的只是别人的恶意攻击而已

网卡的MAC地址也可以随便改变的,自己去搜一下就知道了

mca地址也是可以改的,无需更换网卡

原帖由 BingQ 于 2006-2-7 11:36 发表至于判断作弊有比这个更好的办法
我想应该是这样的。

楼主,如果不在一个局域网,你能够获取MAC地址,那我佩服你。
不要迷信Google的技术,Google不是靠技术取胜。
