Lightweight 4over6 is an extension to DS-Lite. This mechanism moves the translation function from the tunnel concentrator (AFTR) to initiators (B4s), and hence reduces the mapping scale on the concentrator to a per-subscriber level. To delegate the NAPT function to the initiators, port-restricted IPv4 addresses are allocated to the initiators.
