Both DNS return AAAA records. I am not sure why this choice of DNS
should make a difference.

host -v ip6.me |grep AAAA
			IN	AAAA
	9306	IN	AAAA	2001:4838:0:1b::201
host -v ip6.me 8.8.8.8|grep AAAA
			IN	AAAA
	10800	IN	AAAA	2001:4838:0:1b::201
host -v ip6.me 79.79.79.78|grep AAAA
			IN	AAAA
	300	IN	AAAA	2001:4838:0:1b::201

I can only speculate that the difference is the order of A and AAAA records received. And that is only speculation as I have no evidence that ordering is used by some applications.
