+Summary: get IP-Address
+
+Description of Problem: 
+ 
+I am not sure whether this is an bug. The following code does not 
+function under Linux, but in Windows. I use Mono 0.17 (Windows and 
+Linux): 
+ 
+using System; 
+using System.Net; 
+using System.Text; 
+ 
+namespace IP_Adresse 
+{ 
+ public class MainClass 
+ { 
+  public static void GiveIP() 
+  { 
+   String lineBreak=Environment.NewLine; 
+   StringBuilder stringBuilder=new 
+    StringBuilder("IP-Adressen").Append(lineBreak).Append(lineBreak); 
+   IPHostEntry hostInfo = Dns.GetHostByName("localhost"); 
+   IPAddress localAdress = hostInfo.AddressList[0]; 
+   stringBuilder.Append(hostInfo.HostName). 
+    Append(": ").Append(localAdress).Append(lineBreak).Append(lineBreak); 
+   hostInfo = Dns.GetHostByName(hostInfo.HostName); 
+   stringBuilder.Append("Netzwerkadressen:").Append(lineBreak); 
+   foreach(IPAddress ipAdress in hostInfo.AddressList) 
+   { 
+    stringBuilder.Append(hostInfo.HostName). 
+     Append(": ").Append(ipAdress).Append(lineBreak); 
+   } 
+   System.Console.WriteLine(stringBuilder.ToString()); 
+   System.Console.Read(); 
+  } 
+ 
+  public static int Main(string[] args) 
+  { 
+   try{MainClass.GiveIP();} 
+   catch (System.Exception ex) 
+   { 
+    System.Diagnostics.Trace.Write(ex); 
+    return 1; 
+   } 
+   return 0; 
+  } 
+ } 
+} 
+ 
+Actual Results: 
+ 
+Program prints: 
+ 
+IP-Adressen 
+ 
+localhost: 127.0.0.1 
+ 
+Netzwerkadressen: 
+localhost: 127.0.0.1 
+ 
+ 
+Expected Results: 
+ 
+e.G: 
+ 
+IP-Adressen 
+ 
+betty: 127.0.0.1 
+ 
+Netzwerkadressen: 
+betty: 193.159.22.120 
+ 
+I get always the name "localhost", not the real hostname. 
+The IP of dial in connection (for me ppp0) is always 127.0.0.1 
+But under Windows it functions. 
+ 
+How often does this happen?  
+ 
+Always. 
+
