The invention relates to a method, an addressing server and a computer product for supporting the provision of communications services by means of an IP communications network. A request message R with a hyper-address, which is formed from a service indicator of a communications service and a service-provider-independent universal address of a subscriber, is transmitted via the IP communications network to an addressing server. The addressing server generates from the service indicator and the service-provider-independent universal address of the subscriber a service-provider-specific hyper-address of the subscriber by means of access to a service provider porting database. This service-provider-specific hyper-address of the subscriber is converted into an IP address for the provision of this communications service.
