My GPRS modem has got a sim card. it can connect Web. Web service give it a ip number. i need it. like that: http://www.your-ip-address.com/

How can i do that C#?

Answer 1

You can get a list of your IP addresses via DNS using the following code:

var name = Dns.GetHostName();
var entry = Dns.GetHostEntry(name);
foreach (var address in entry.AddressList) {
   Console.WriteLine(address);
}

If you want the IP address as a property of the hardware, you can use the System.Management.ManagementClass with the name Win32_NetworkAdapterConfiguration. See http://msdn.microsoft.com/en-us/library/system.management.managementclass.aspx for details.
