Defining IPv6 network as IPV6_NETWORK = "fd00::1:1:1:1" is not quite 
correct. Here you have specified the IPv6 address, not network.

There are other variables that should be defined as well: 
LHOST_IPV4_HOST, RHOST_IPV4_HOST, LHOST_IPV6_HOST, RHOST_IPV6_HOST, i.e. 
host specific parts.

In your case IPv6 network is "fd00::/64", and I would set vars as follows:
IPV6_NETWORK = "fd00"
LHOST_IPV6_HOST=":1:1:1:1"

After that you will get fd00::1:1:1:1/64 address in the tests 
(${IPV6_NETWORK}:${LHOST_IPV6_HOST}).

Alexey
