to cut the long story short and before we try to debug this in detail;
if you try to reach all these addresses on the local machine, does that work, eg. if you ping6 2001:abcd:f:abcd::100[0-5] from that host itself?

Is it just that you cannot reach them from outside your local network?

         Stop bit received. Insert coin for new address family.
