That means a join is being attempted to a multicast group which is not
yet created. These are typically groups that you can ignore. They are
benign.

The two above are both IPv6 multicast groups. The first one ends in 0x16
and the second one 0x2. I think those are IGMP and all routers multicast
groups.
