This question gets asked quite a bit. You'd think there would be a better answer by now, eh?

Well, the reason that I don't think there is a really great answer is that, eventually, after lots of wrangling, 95% of the time the reason that this information was requested in the first place was due to a misunderstanding of how TCP/IP works, or something similar.

Asking for "your own" IP address is pretty much guaranteed to give you a "solution" that doesn't work in quite a few situations.

So you might want to tell us why you want this because most of the time there is a better solution that doesn't involve solving this particular problem. (:
