您可以使用以下代码获取客户端的IP地址，

You can get client''s IP address using following code,

Request.UserHostAddress

MAC地址不在客户端请求标头中，因此您唯一拥有的客户端要使用的IP地址.除非服务器与客户端位于同一网段，否则无法获取客户端的MAC地址.

将会发生的是，您将获得客户端的IP地址，尝试使用ARP将其解析为MAC，但是随后您发现返回的MAC对于几乎所有客户端都是相同的(取决于网络布局)，它是路由器近端接口的MAC.这是从服务器到客户端的第一跳.

The MAC address isn''t in the client request headers, so the only thing you''ve got in the clients IP address to use. You can''t get the MAC address of the client unless the server is on the same network segment as the client.

What''ll happen is you''ll get the clients IP address, try to resolve it to a MAC using ARP, but then you''ll find that the MAC you get back is the same for just about all of your clients (depending on network layout) and it''s the MAC for the routers near-side interface. This is the first hop from the server back to the client.
