I think you can setup a domain name with some one like ddyns.org to your host name or somthing so if you have a dynamic IP it doesnt matter to much as you can just use the domain name which always goes to the right place ..... not sure if thats correct but i know ajbrun has done that, its a great idea because it means even though hes on a dynamic ip he can still host a ftp/webserver for firends and they dont need a new ip every time they want to access it
