Hi, I have pi-hole on a Pi and set my router DNS to point to it's IP address as described by the pi-hole install stuff.
The Internet access seems to be working OK, but, from my Ubuntu I'd like to see which DNS server is being used beyond the Pi. When I set pi-hole up, I selected DNSWatch as the default downstream (or upstream) but would like to see that it is being used.
Also, I'd like to see what DNS is being used when pi-hole is turned off. There is a delay of about 5-seconds and then my Acer/Router finds a DNS server to use.
I can add 2 more DNS servers in my dd-wrt router so was thinking of adding OpenDNS as a fall back if the pi-hole is down.
Is there a way to query the Pi, or my Ubuntu to get the outside DNS?

If you are running a more modern linux and want an authoritative answer try:
systemd-resolve --status
It will show all adapters and what each adapters DNS server is. So you can troubleshoot OpenVPN problems...etc.
