1. A method comprising:
receiving, from an application function of a communications network by a stack redirect function of the communications network, the stack redirect function including at least one processor, a redirected request for an application function-specific user endpoint identifier that is unique to a combination of a user endpoint device and the application function, where the redirected request includes an identifier of the application function and an internet protocol version 6 address associated with the user endpoint device;
querying, by the stack redirect function, a binding support function of the communications network for a subscription permanent identifier associated with the internet protocol version 6 address associated with the user endpoint device;
querying, by the stack redirect function, an application function-specific management function for an application function-specific user endpoint identifier associated with the subscription permanent identifier and the identifier of the application function; and
forwarding, by the stack redirect function, the application function-specific user endpoint identifier associated with the subscription permanent identifier and the identifier of the application function to the application function.
