Obtain a MAC address from a connected socket

[Jeronimo Bertran]

Hello,

We have developed a socket tcpip server in .net that accepts calls from
clients. Using the connected socket we are able to use the
Socket.RemoteEndPoint to obtain the IP address of the client. Is there any
way to obtain the MAC address for the client?

Thanks

Jeronimo

That's not really practical... The only tools that can query the MAC
address work within a subnet (because a remote IP would resolve to the
router's MAC)

The client MAY not even have a MAC address, they could be using a protocol
like SLIP or PPP.

Hi Jeronimo,

As Emmet and Jim has mentioned, the clientside could have discretionary
sub net structure and MAC address only make sense for the clientside's
local network area. In fact, the subnet is just used for local network area
and is not visible to the external network. If your application's client
side are all in the same local network environment, that'll make some sense.

Thanks,
