商业源码 怎么查看连接路由器的各个客户端的MAC地址
在路由器的DHCP客户列表中即可查看到这些信息。
1、用浏览器进入路由器的web管理页面，一般地址为19216811，输入用户名和密码进入web管理页面。
2、一般在“DHCP服务器”——“DHCP客户列表”中即可查看到，如下图所示，第一列是主机名，第二列是内网IP地址，第三列即是MAC地址。
很简单取得对方IP后,将其传入下面函数GetMACAddress即可得到string类型的MAC地址:

js是在客户端运行的，asp代码是在服务器运行的， 没有办法获得客户端的mac。
用javascript就可以，参考代码如下：
function getMac(){var locator = new ActiveXObject ("WbemScriptingSWbemLocator");
var service = locatorConnectServer("");
var properties = serviceExecQuery("Select from Win32_NetworkAdapterConfiguration Where IPEnabled =True");
var e = new Enumerator (properties);
{
var p = eitem();
var mac = pMACAddress;
return mac
}
}
alert(getMac())
