All you do is tell IPAPub where your ISP's FTP server is located for publishing your personal web pages. Give your login, password and a few other additional bits of information if you like and IPAPub will always update a web page that you specify with your current IP address.
Our Review: I.P. Address Publisher is a small, free and simple program which does exactly what it says. If this is what you need then the easy-to-use layout and free pricetag will make this a worthy download.
