Hi Gerd,
it means some one else is sending out ipv6-addresses in your network. as it looks like they came in from a hotspot, that is something you can discard or block it by some filters. but as long as nobody uses v6 in your network you should not worry about it.
it is definitely not a hacking attempt, more a misconfigured client.
