Hi John,
I think that when you're specifying the pool as a network ({ "pool":
"aaaa:bbbb:cccc:dddd::/80" }), kea is assuming that the very first IPv6
is a "valid" one.
Try specifying the pool as a range of IPv6, or, at least configure an
exception (not to serve) the address ...::0 of /80.
Regards,
Joelson
