To get the user's IP address, you can use what others have suggested. However, you cannot obtain a user's MAC address unless they are directly connected to your router.

If you want to uniquely identify your user, you should try to identify them by a combination of IP, OS and some other specific data. However, this will still not be entirely reliable.

If you allow registration on your website, then you could identify users by their e-mail addresses.

There is a question on StackOverflow that seems to be about the same thing: How do I uniquely identify computers visiting my web site?. An answer there suggests the usage of cookies. You might want to check out the following article: Beginner's Guide to ASP.NET Cookies.

You can't get the MAC Address of your client

to get the IP address use

string ipaddress;
ipaddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
if (ipaddress == "" || ipaddress == null)
    ipaddress = Request.ServerVariables["REMOTE_ADDR"];
