        Console.WriteLine(adapter.Description);
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        Console.WriteLine("  Interface type .......................... : {0}", adapter.NetworkInterfaceType);
        Console.WriteLine("  Operational status ...................... : {0}",
            adapter.OperationalStatus);
        string versions ="";

        // Create a display string for the supported IP versions.
        if (adapter.Supports(NetworkInterfaceComponent.IPv4))
        {
             versions = "IPv4";
         }
        if (adapter.Supports(NetworkInterfaceComponent.IPv6))
        {
            if (versions.Length > 0)
            {
                versions += " ";
             }
            versions += "IPv6";
        }

        Console.WriteLine();
    }
    Console.WriteLine();

Remarks

The description is human-readable text that describes the network interface. The information included in the description depends on the capabilities of the operating system. On Windows, it typically describes the interface vendor, type (for example, Ethernet), brand, and model. On other platforms, it may be as brief as the name of the interface, such as eth0.
