You cannot. IPv4 addresses are not equivalent or related to IPv4 addresses. You can only convert when a relationship exists.

You can, of course, create networks based on IPv6 and have them talk to IPv4 networks. And you can tunnel IPv6 over an IPv4 network. However, neither of those involves conversion of address schemes.

Hi Chirs,

I have seen that if i use "ipconfig" command in Windows 2008 then i got two different IP one is for IPv6 and another is IPv4. So there must be some way to get IPv4 IP in IPv6 computer. So, can you show me any way to get this IPv4 IP using C#? That can be solved my problem.

Thanks.

If you're on the system, or have access to WMI on the system then you can grab the assigned addresses using WMI (Management Class).

Is that what you're looking for? If so, I have a bit of sample code I can modify to show you at least one way of doing it.

Hi Chris,

I have access as i am using those resources as Administrator, so can you help to have some code in C# to get both IP address (IPv6 and IPv4) from an computer running on Windows2008 or vista.

Thanks.

Sure :)

I could only test this one Windows 2008, no vista machines kicking around, but it works for me.

You'll have to add a reference to System.Management in your project. The computerName set to "." means it runs against the local machine.

Chris

static void Main(string[] args)
{
  String computerName = ".";
  ManagementScope wmiManagementScope = new ManagementScope("\\\\" + computerName + "\\root\\cimv2");
  SelectQuery wmiQuery = 
    new SelectQuery("SELECT IPAddress,IPEnabled,Description FROM Win32_NetworkAdapterConfiguration WHERE " +
    "IPEnabled='True'");
  ManagementObjectSearcher wmiQueryResults = new ManagementObjectSearcher(wmiManagementScope, wmiQuery);
 
  try {
    wmiManagementScope.Connect();
  } catch (System.UnauthorizedAccessException) {
    Console.WriteLine("Access Denied");
  }
 
  foreach (ManagementObject wmiQueryResult in wmiQueryResults.Get()) {
    Console.WriteLine(wmiQueryResult["Description"].ToString());
    String[] ipAddresses = (String[])wmiQueryResult["IPAddress"];
    foreach (String ipAddress in ipAddresses) {
      Console.WriteLine(ipAddress);
    }
  }
}
