Abstract: Certain examples described herein make use of an intermediate network device (110) in a service provider network (104) to enable the modification of network requests to provide enhanced functionality. These examples use a rotating network identifier that is inserted into a network request that is receivable by a server device (108) located outside of the service provider network (104). An association between the network identifier and data originating from the service provider network may be effected via a mapping that exists for the predefined time period. In certain examples, a data broker (114) is introduced within the telecommunications network (100). The data broker (114) may be configured based on the aforementioned mapping between the network identifier and data originating from the service provider network. The data broker is adapted to use the mapping to provide data to the server device (108).
