[Twisted-Python] Cannot perform IPv6 Link-Local Multicast on Twisted

I am trying to use the .joinGroup() by passing the IPv6 link-local multicast add. ff02::1 but get DNS lookup failure error. I am trying to use the UDP multicast example on the twistedmatrix.com website and simply replacing the IPv4 multicast address with the IPv6 one. I have also posted a query on StackOverflow: http://stackoverflow.com/questions/36034258/ipv6-link-local-multicast-on-twi... I am newbie on Twisted and some suggestions would be appreciated. Thanks a lot Shan Shantanoo Desai (Shan Desai)
