ManagementScope scope = new ManagementScope(@"\\.\ROOT\CIMV2");
ObjectQuery query1 = new ObjectQuery("SELECT * FROM Win32_NetworkAdapterConfiguration");
ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(scope, query1);
ManagementObjectCollection queryCollection = searcher1.Get();

foreach (ManagementObject m in queryCollection)
{
    string[] addr = (string[])m.GetPropertyValue("IPAddress");
    if (addr != null)
    {
        Console.WriteLine(addr[0]);
    };
}
