Duplicate Address Detection: Significance, Attacks and its Solutions

IoT is a platform that allows various things to connect and communicate with one another. IPv6 is used to simplify the addressing process in order to address the IPv4 limitation. Each device needs an IPv6 address, which needs to be distinct and unique, in order to join a network. The DAD procedure is a useful tool for detecting address duplication in a network. It is necessary for each IoT object to create a unique IPv6 address when it joins the network in order to communicate with other nodes. The practice of detecting duplicate addresses is employed in order to ensure the unique address to each object before joining the network. This paper discusses the significance of the DAD process, potential dangers to the DAD process, and several author-provided solutions. This paper also presents different lessons learned from the literature and present future research directions towards the DAD process.
