If you're going to go that route, it's much better to use 0.0.0.0 so that you're not sending HTTP requests to your machine. Otherwise, anything listening on port 80 (or 443, in some cases) will be receiving the requests intended for Facebook.

Good point, though that leads to a really simple hack to see part of what gets sent to facebook - just hook up something listening on those two and look at the logs? I like ngrep for that kind of thing, but it's perhaps perverse overkill.

Noted, thanks!
