Abstract: A method and system are provided for directing a client to a preferred service instance. At creation of a service instance, the service binding attribute of the created instance is extended to include assigned domains and associated priorities. There are then two phases to directing a client to the preferred service instance. The first phase is compilation of a list of domains and priorities for the service in response to a query. Upon completion of the first phase, a second phase is executed to determine a preferred service for the client by comparing fully qualified domain name entries and assigned priority entries.
