Hy everyone, I have a PiHole instance running on my home server, and I changed my router (Fritz box) DNS in order to use my PiHole. Everything runs great.

I was wondering if I can put another DNS provider on my “alternative DNS server” in my router, in order to have a fallback alternative in case my server is down, or if I should avoid it.

I’m asking this because I don’t know if the request will be handled in parallel between the two DNS provider (that would make my PiHole useless) or not. Thank you.

    mary DNS Server: Clients will first attempt to use the primary DNS server specified in their network settings. This ser

    What’s the point tho? If your PiHole fails you need to know otherwise you could be risking days / months of web surfing in the fallback DNS server without even noticing it.

    As for a reply, there’s no RFC that specifies that a specific order is applied to DNS servers. So in short, you can’t have a fallback that is reliable and most operating systems will just load balance or opportunistically pick between the two.

      Thank you, this is what I was worrying about. As for the “why”, even if my server is quite stable, a shutdown may be necessary and sometimes slowdowns with pi-hole happened. Some redundancy would have been better.
