I\'m looking for a solution to find out about the MAC number of a user using asp.net website. I know you can get an IP address (don\'t know why but it can\'t be complicated)
I have a similar problem (I'm using the client device MAC address as a key to target different content at different devices). This thread has been useful. Given that there seems to be no way to do this implicitly I have instead included the MAC address as one of the parameters passed by the client to the web service.
(N.B. This is not a generic answer, it only makes sense where the client and server are tightly integrated and where there is scope for passing data with the call.)
