You can't - MAC addresses do not travel beyond the router, so you have to run code on the client. And the only ways to do that I know of are IE specific.

And to be honest, it probably won't help you: MAC addresses aren't unique (they only have to be unique within a LAN segment) and they are very easy to spoof. So if you are planning on using MAC for identification / authorization, I would recommend you forget it and install a cookie instead.

i got it here i used

(using System.Runtime.InteropServices;)
[DllImport("Iphlpapi.dll")]
private static extern int SendARP(Int32 dest, Int32 host, ref Int64 mac, ref Int32 length);
[DllImport("Ws2_32.dll")]
private static extern Int32 inet_addr(string ip);
protected void Page_Load(object sender, EventArgs e)
{
try
{
string userip = Request.UserHostAddress;
string strClientIP = Request.UserHostAddress.ToString().Trim();
Int32 ldest = inet_addr(strClientIP);
Int32 lhost = inet_addr("");
Int64 macinfo = new Int64();
Int32 len = 6;
int res = SendARP(ldest, 0, ref macinfo, ref len);
string mac_src = macinfo.ToString("X");
if (mac_src == "0")
{
if (userip == "127.0.0.1")
Response.Write("visited Localhost!");
else
Response.Write("the IP from" + userip + "" + "
");
return;
}

while (mac_src.Length < 12)
{
mac_src = mac_src.Insert(0, "0");
}

string mac_dest = "";

for (int i = 0; i < 11; i++)
{
if (0 == (i % 2))
{
if (i == 10)
{
mac_dest = mac_dest.Insert(0, mac_src.Substring(i, 2));
}
else
{
mac_dest = "-" + mac_dest.Insert(0, mac_src.Substring(i, 2));
}
}
}

Response.Write("welcome" + userip + "
" + ",the mac address is" + mac_dest + "."
