receiving, by a session management node of the wireless network, for a first packet routing node of the wireless network, a first indication of supported internet protocol (IP) traffic type, wherein the first indication of supported IP traffic type indicates support for a first IP traffic type or support for a second IP traffic type different from the first IP traffic type;
allocating, by the session management node, to the first packet routing node, a first set of IP addresses based on at least the first indication of supported IP traffic types, wherein allocating the first set of IP addresses comprises allocating only supported IP addresses and withholding allocation of unsupported IP addresses;
providing, to the UE, using an IP address of the first set of IP addresses, the data traffic session through the first packet routing node;
receiving, by the session management node, from the first packet routing node, a request for an additional allocation of IP addresses; and
