Replying to my own post... Problem was with our ISP. Resolved now . On Mon., 12 Aug. 2019, 17:42 Malcolm Faed, <malcolm@avcomm.com.au> wrote:
Hi all,
Sorry in advance for the partial MT post, but I am hoping someone can assist.
We have our own AS and an IP range routed through a MT. Clients connected to our IP range are receiving 'query refused' from a NS lookup using google DNS 8.8.8.8.
Other DNS servers (8.8.4.4 / 1.1.1.1 / 9.9.9.9) etc work fine.
For the router itself and NAT I use 9.9.9.9 so never noticed until clients started connecting.
Is there anything special I need to do to use Googles DNS via our IP range?
Below is a debug log from Windows nslookup.
Thanks in advance for any clues.
Cheers, Mal
