And it's about the public IPv4 address allocation, NOT about IPv4 address and IPv6 address mapping. So there is no state. Please read the draft of DHCPv4 over IPv6 for clarification. LW4over6 needs to maintain the binding table on TC. That's stateful. Actually in MAP 1:1 mode there will be a binding table right? Here comes the question: what will you do if there are new comers or some users leaving the network? > cheers, > --satoru
