Answer 1

If you're trying to get your internet ip, you have essentially two options:

1) DIY - Determine the correct strategy to retrieve this data from your OS.

2) Phone a friend - Set up a server somewhere on the internet with a small server that will, when connected to, tell you your IP address. This would be little more than a few lines of code (and I expect such a thing exists already).
