Differentiate VMware network adapter from physical network adapters -or- Detect Virtual Network Adaptor

Question

I have to differentiate between the real addresses and the VM addresses using any Windows API. I\'m using GetAdaptersAddresses API to populate a list of IP addr

You can pass NetworkInterface in below method and it will return boolean to indicate that the NIC is Physical or not.

        private static bool IsPhysicalAdapter(NetworkInterface ni)
        {
           bool isPhysical = false;

           ManagementObjectSearcher searcher = new 
                              ManagementObjectSearcher(@"root\CIMV2", 
                              string.Format(@"SELECT * FROM  Win32_NetworkAdapter 
                              WHERE GUID='{0}' AND NOT PNPDeviceID LIKE 'ROOT\\%'", 
                              ni.Id));

           foreach (ManagementObject share in searcher.Get())
           {
                isPhysical = 
                   Convert.ToBoolean(share.Properties["PhysicalAdapter"].Value);
                break;
           }

           return isPhysical;
        }
