KOVAN* is an medium-interraction virtual IPv6 honeypot. KOVAN is designed to work both on local area and wide area. In wide area; KOVAN can emulate complex network topologies with lots of nodes and routers. In complex networks, KOVAN uses routing protocols  to dynamically distribute routing information to virtual hosts. In local area; administrator can define nodes and distribute them among real nodes. The advantage of LAN mode is that it is hard to detect and distinguish such honeypots from real computers.
