Thanks for the tests that show the NODATA is from the authoritative nameserver. To clarify, Google DNS does not filter either AAAA or any of these domains. Yunhong On Tue, Jul 14, 2015 at 8:05 PM, Yang Yu <yang.yu.list@gmail.com> wrote:

Surely Microsoft has IPv6 connectivity? Is there a problem with my dns, or is Microsoft not available over v6?

probably not Google DNS filtering

I get different IPs for n0dspb.akamaiedge.net / n0dscb.akamaiedge.net every time.
So it depends on source IP of the query and which akamai DNS server is answering?
