Esko, DHCPv6 for 6LoWPAN network. In the current version of I-D, there's one chapter (3.2.1) describing "IPv6 Address Configuration", which mentioned "Stateless autoconfiguration". Stateless autoconfiguration is defined in RFC4862, which is different from "stateful autoconfiguration" (aka DHCPv6). Compared with 6LoWPAN over BT-LE, draft-ietf-6lowpan-nd has defined the mechanism to configure IPv6 addresses for 6LoWPAN over 802.15.4. In draft-ietf-6lowpan-nd-17, there're several assumptions for 6lowpan-nd. It says "All nodes in the network have an EUI-64 interface identifier in order to do address auto-configuration and detect duplicate addresses." Also, draft-ietf-6lowpan-nd introduces the Address Registration mechanism and the optional DAD mechanism. DHCPv6 is not optimized for low-power and lossy networks including 802.15.4 and BT-LE. I think it is necessary to make the "IPv6 address configuration" for 6LoWPAN over BT-LE clear in the future revision.
