The automatic address configuration simplifies the IP configuration task in IPv6 networks. Two protocols have been developed for automatic address configuration: Neighbor Discovery Protocol (NDP) and Dynamic Host Configuration Protocol for IPv6 (DHCPv6). However, these protocols create security holes in a network that expose network nodes to various attacks such as redirect and DoS attacks. In this paper, we propose a new hybrid address autoconfiguration to automate address generation and assignment in IPv6 networks. This autoconfiguration will protect network nodes from address misconfiguration and the mentioned attacks, by managing the flow of NDP and DHCPv6 messages.
