They don’t seem to have reverse DNS set up correctly for the resolvers yet. Nor do the host names have AAAA records pointing to the IPv6 addresses.

The funny thing is that they’re reusing the IPv4 octets, that look like decimal notation, but in the hexadecimal Interface ID:
2a13:1001::86:54:11:100
Not to mention the unfortunate association with IPv4 in the service name. When will DNS6EU be released? More to the point, “for” is a distinctly English word, so has “4” become an international chatspeak stand-in?
I read it as "DNS for EU" not as a hint towards IPv4.
