However, IPv6 natively provides for autoconfiguration of IP addresses through IPv6Neighbor Discovery Protocol (NDP) and through the use of Router Advertisement messages. Thus, therole of DHCPv6 within the network is different than that of DHCPv4 in that it is less relied upon for IPaddress assignment.DHCPv6 server and client interactions are described by RFC 3315 [6]. There are many similaritiesbetween DHCPv6 and DHCPv4 interactions and options, but the messages and option definitions aresufficiently different such that there is no DHCPv4 to DHCPv6 migration or interoperability.DHCPv6 incorporates the notion of the “stateless” server, where DHCPv6 is not used for IP addressassignment to a client; rather, it only provides other networking information such as DNS, NTP, and/orSIP information. The stateless server behavior is described by RFC 3736 [7], which simply containsdescriptions of the portions of RFC 3315 that are necessary for “stateless” server behavior. In order for arouter to drive a DHCPv6 client to utilize stateless DHCPv6, the “other stateful configuration” optionmust be configured for neighbor discovery on the corresponding IPv6 router interface. This, in turn,
