如何获取ASP.NET浏览网站的客户端的mac地址 [英] How to get mac address of client that browse web site by ASP.NET

问题描述

大家好，

该代码将返回托管mac地址，但我想要客户端系统mac地址。



我尝试过：

Hello every one,
thats code will be return hosting mac address but i want client system mac address.

What I have tried:

string macAddresses = string.Empty;
NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
macAddresses = nics[0].GetPhysicalAddress().ToString();

推荐答案

你不能：如果可以，它就无济于事。

MAC地址不会传输到连接LAN网段和互联网的路由器之外 - 它不是'建立PC和路由器之间的初始连接并分配本地IP地址后需要或使用。

此外，MAC地址不是唯一的：它们只需要在PC和路由器所在的网段。而且它们难以置信地欺骗！



在客户端使用cookie，结合良好的安全性 - MAC寻址对你没有帮助。

You can't: and it wouldn't help if you could.
MAC addresses are not transferred beyond the router which connects the LAN segment to the internet - it isn't needed or used after the initial connection between the the PC and the router is established and a local IP address is assigned.
In addition, MAC addresses are not unique: they just have to be unique within the network segment that the PC and router are on. And they are unbelievably easy to "spoof"!

Use a cookie on the client, combined with decent security - MAC addressing will not help you.
