How to get machine ip when there is no DNS?

[ankursaxena]

Hi I wanted to get the ip addr of my machine ( not 127.0.0.1) but whatever is assigned in the prvt network but i dont have a dns hocked for that.

Thanks

So what does the following return for you?

string strHostName;
			strHostName = System.Net.Dns.GetHostName();

			IPHostEntry ipEntry = System.Net.Dns.GetHostByName (strHostName);
			IPAddress [] addr = ipEntry.AddressList;
          
			for (int i = 0; i < addr.Length; i++)
			{
				System.Windows.Forms.MessageBox.Show("IP Address: " +  i + addr[i].ToString());
			}

For me it returns the correct IP that I have been assigned (not 127.0.0.1).

are you connected to any dns? or is your machine standalone and on no network or a private network?

Thanks for the code...

If you're not connected to a network, then pretty much by default your only interface will be "localhost" at 127.0.0.1

If you are connected to a network, but don't have DNS services, then you have a problem (aside from having to type in IP addresses to get anywhere, that is).

Try using the .Resolve method.

I'm not connected to a network - the IP address that it picks up for me is the one assigned by my ISP for my internet connection.

Uhh, yes you are connected to a network -- the internet. Via your ISP.

Yes sorry - I meant I wasn't connected to any local network.
