The description of dynamicIP - Play With New Friends

So you've got ADSL but your ISP gives you a leased address. DynamicIP is a tool for publishing your address to a website, email or DynDNS.org. It keeps your ADSL connection up, even if your modem goes offline. If DynamicIP can't publish the latest address, the system is rebooted. Full instructions are provided, describing how to use DynamicIP and how to integrate your current IP setting into your Web site.
