I turned on OS X's built in web server feature called "web sharing" in the system prefs, and it says that this "allows users of other computers to view web pages ... on this computer" by going to http://192.#.#.# (except it says actual numbers in place of #). I'm able to see my home-served webpage on all of my computers at home by opening up that URL in safari, and I can see it on my iPod Touch when I'm at home. BUT when I'm somewhere else and not using my home wifi network, when I load up that http://192.#.#.# page it just says "server could not be reached at that address." Is my ISP blocking me from serving HTTP requests? Is there some way I can set it up so that I can reach my home-served webpage when I'm away from my apartment?
