Its really up to the engineering team for that implementation. I would integrate v4 and v6 and duplicate as little as possible. At least all data structures so the algorithm for update/replace/delete was the same function module and not duplicated once for tcp and once for udp and yet again for SCTP. Then there is the emerging RDMA the router might want to use for storage. Treating all addresses as 16bytes (v4 and v6) works and will perform. Also all the traffic shaping, classification, et al on hardware would make the hardware engineers job a lot easier and thats a performance win too to support both address types.
