Except queries from 96.31.0.5 and 199.120.69.24 reliably return the AAAA while queries from 96.31.0.20 do not. And we're all the same ISP, and in the one case, from the same /24. I don't think Google is that granular. And we do have good IPv6 connectivity.

Didn't google have some kind of ISP whitelisting for handing out AAAAs? Ah yes... https://developers.google.com/speed/public-dns/faq mentions it: "Note that you may not receive IPv6 results for Google properties. To optimize the user experience, Google only serves AAAA records to clients behind ISPs with good IPv6 connectivity." _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
