I am making a web site that I can put games, music, live chat and tons of other things on there that all my friends and other people that visit the site can look at and enjoy, but I would like a few pages (live chat and blog) to be private to my friends IP's but I do not know how to do this. Currently, on the web site, I am using HTML5, CSS and JavaScript and am still learning the more complex languages like PHP and others but I am still open to trying. The site is currently hosted on my computer using a DNS address that others on my LAN can access but I will soon be moving my script to a proper hosting service once the web site is ready for release.
