exactly what is your definition of "hybrid"?

NDN can/should run over IP as an overlay, i.e. using IP to connect up (isolated) NDN nodes. does this match your hybrid definition?

NDN treats IP as offering virtual link function.
i.e. you can set up an UDP/IP tunnel between two NDN nodes, so the two NDN nodes can exchange Interest/data packets.
