The DynDNS Service is a DynDNS client for Windows operating systems, which installs itself as a Windows service, permanently monitors the current status of the public IP address of your Internet connection or your UPnP-enabled DSL router and updated as necessary in their DynDNS provider. The update can be done simultaneously for multiple domains at different DynDNS providers.

Despite constantly changing IP addresses, it is still possible to access Internet , always under their domain name. The service of their home server can be made available over the Internet.
