Get IP address and dns IP of network card

Question

Guys,

I have seen a lot of examples of how to get the IP addressses of the local network card but they only get the local IP and not default gateway etc. I would like to get the following info and display onto labels on the form:

IP
Subnet mask
Gateway

Preffered DNS server
Alternative DNS

Is it possible? I would run this on form load event.

Yes you can get this using ManagementClass if it is DESKTOP application. Here is the detailed articles. Get MAC Address of Network Card using WMI and C# http://www.codeproject.com/Articles/5697/Configuring-TCP-IP-Settings-using-WMI-and-C

You should be able to get this information using WMI and the Win32_NetworkAdapterConfiguration class: http://msdn.microsoft.com/en-us/library/aa394217(v=vs.85).aspx I found this article which shows how to get the ipaddress, subnet and gateway information. Notice that all info is returned in a string array. To use the code you need to add a reference to System.Management.dll and also need this using directive: using System.Management; at the top of the file. http://www.codeproject.com/Articles/5697/Configuring-TCP-IP-Settings-using-WMI-and-C For DNS info, I'd use the DNSServerSearchOrder property. The preferred DNS server should be the one at index 0 in the array.
