2nd DNS is not working in CRS125-24G-1S-2HnD

RouterOS General

Hi all,

I have 2 DNS servers (IP/DNS) configured at Mikrotik

1st: 192.198.1.2 → Rpi3 Pi-Hole, which is awesome as you know
2nd: 8.8.8.8 → Google standard, just in case 1st one is not working
Today Rpi3 is totally KO and my WiFi and some computer stopped working… I thought that if first DNS is not working, my Mikrotik would help with second one. Is that correct?

In my case I needed to fix my Rpi3 in order to have my Network to work again.
Can you please help me?

Thank you

Only when the first one does not answers several times (about 15 times) then the second DNS is used till that one does not answers.

Each client uses it’s own counter. If your Mikrotik is the sole DNS for the clients then you have one counter.
