The recommended way to do this with V2.0 of the framework is to use the System.Net.NetworkInformation namespace.. This sample should get you started: public class NetInfoTest { public static void Main() { try { DumpIPAddresses(); NetworkChange.NetworkAvailabilityChanged += OnNetworkAvailabilityChanged; NetworkChange.NetworkAddressChanged += OnNetworkAddressChanged; Console.ReadLine(); } catch (Exception e) { Console.WriteLine(e); } finally { Console.ForegroundColor = ConsoleColor.Green; Console.BackgroundColor = ConsoleColor.Black; } } public static void OnNetworkAvailabilityChanged(object sender, NetworkAvailabilityEventArgs e) { if (e.IsAvailable) { Console.ForegroundColor = ConsoleColor.Green; Console.WriteLine("Network Available"); } else { Console.ForegroundColor = ConsoleColor.Red; Console.WriteLine("Network *NOT* Available"); } } public static void OnNetworkAddressChanged(object sender, EventArgs e) { Console.ForegroundColor = ConsoleColor.Red; Console.BackgroundColor = ConsoleColor.Yellow; Console.WriteLine("Address change event at {0}", DateTime.Now.ToString()); Console.ForegroundColor = ConsoleColor.Green; Console.BackgroundColor = ConsoleColor.Black; DumpIPAddresses(); } public static void DumpIPAddresses() { //1. Get All Network Interfaces NetworkInterface[] NetworkInterfaces = NetworkInterface.GetAllNetworkInterfaces(); //2. Loop over the interfaces foreach (NetworkInterface NI in NetworkInterfaces) { //3. Select Ethernet Interface if (NI.NetworkInterfaceType == NetworkInterfaceType.Ethernet) { Console.WriteLine(Environment.NewLine); Console.WriteLine(En
