After I have upgraded to Kali Linux Sana I have noticed that the THC-IPV6 kit ,with tools such as flood_router26, has disappeared. If somebody could tell me where it is, or how to install it again, I would be very thankful.  
THC-IPV6 Kali Linux 2.0
kali linux;ipv6
The THC-IPv6 tools are still there:# locate alive6/usr/bin/atk6-alive6/usr/bin/atk6-inject_alive6...# locate flood_router26/usr/bin/atk6-flood_router26...Moreover, the source code for the tools is avalible on github
