    Console.WriteLine("Multicast Addresses");
    NetworkInterface[] adapters  = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        MulticastIPAddressInformationCollection multiCast = adapterProperties.MulticastAddresses;
        if (multiCast.Count > 0)
            foreach (IPAddressInformation multi in multiCast)
                Console.WriteLine("  Multicast Address ....................... : {0} {1} {2}", 
                    multi.IsTransient ? "Transient" : "", 
                    multi.IsDnsEligible ? "DNS Eligible" : ""
