Howdy Everyone!

As I am setting up my infrastructure at home using docker I wanted to ask, is it better to have DNS, something like pi-hole, on my main docker swarm or would it be better to have it on a dedicated machine/docker host separate from the rest of my infrastructure?

Thanks for the input!

    If you want to run your own recursive DNS server, why would you run two separate DNS servers?

    I’m not sure I understand your question. A recursive DNS server and a local DNS cache/forwarder/are two different things with two different purposes. You will always need both. You yourself are using AdguardHome and that is just connecting to recursive DNS server upstream. In my scenario you’re just running both yourself instead of you running one and then letting a 3rd party run the other for you.

    Your outbound queries will still be unencrypted, so your ISP can still log them and create an advertising profile based on them.

    You can encrypt the recursive queries through your ISP if you want to. Though the effectiveness of any profiling your ISP would do to you are minimized by Qname minimization that Unbound does by default.

    If you’re just using DoH then you’re just shifting who’s making that advertising profile on you from your ISP to whoever is hosting your upstream recursive DNS server. It doesn’t matter how much encryption you do because on the other end of that encrypted connection is the entity who you’re giving all your queries to.

      Why do you need two separate ones though? Recursive DNS servers also cache responses. Usually the only reason you’d run a local forwarder/cache is if you’re not running a local recursive server.

        For the same reason you’re running AdGuard and not just pointing all your devices at the recursive upstream.

        You’re using AdGuard / Pihole as an ad sinkhole, not just to cache and forward DNS requests. Like if you really wanted to you could hack together something in Unbound to do that, but why would you do that when Pihole already exists? You have two things built for purpose.
