From the developer:
DNS4Me is the dynamic DNS service that you need to start hosting your own Internet services. When you have a dynamic IP address, you need something to associate a static domain name with it to make it easier for visitors to access the services you provide. With DNS4Me, you can take control of your Web site by running your own HTTP server.
