In my application I list all available network adapters...
Code:
..
foreach (NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces())
{
     //add it to UI combobox
}
..
As my app is now being used more and more on Win7, users complain that a lot of 'unknown' network adapters are listed.
It appears these are IPv6 so-called tunnel adapters .

Does anyone know of a way to programmatically detect wether NetworkInterface is such a tunnel adapter ?
