Check out the Microsoft IP Helper API. I'm fairly certain that this is the API they use in their OS apps to display network objects and their configurations. You may need to get the Platform SDK from Microsoft (it's free for downloading) to get the necessary libraries.

Searching through the registry to find network configuration information and supporting multiple versions of Windows can be a nightmare.

Yeah, I thought about it as one of first guesses, but it occured to me 
that it may bring out some problems - if administrator removed 'ipconfig' 
[for any reason] or just blocked it, I've got trouble. Also simple 'using 
different Windows language versions' might not be nice.

And also I just though that...

...Windows has to do it somehow! :-) Anybody has any idea how?

How can I trace API calls?
