Change in TCP/IP properties using C# code

So you chose to repost this question here:
http://www.codeproject.com/Questions/133954/Obtain-IP-address-dynamically.aspx
Now what makes you do something like that? Don't repost! Thank you!

If you have further questions to an answer you're always free to leave a comment with that answer, or you can even choose to modifiy your question. Eventhough for the sake of the thread's readability you should keep those parts included that were referenced in an answer.

@Toli: I already reported his repost as you can see in my comment from today. The repost (see link in my comment) has already been removed. So I removed the "REPOST:" from the title as this is the original post. It's always good form to leave a comment when editing a question, thank you!
