Two piholes at home (redundancy). Those both translate all regular DNS requests to DoH using Cloudflared which rotate through 4 non-isp upstream DoH providers.

The router is set to block all port 53 traffic from leaving the network and handout the 2 pihole IPs to dhcp clients for dns. If a LAN device wants regular dns, it MUST use the lan servers or it’ll get no response. (or it can use its own DoH setup and/or vpn out of the network). This enforces the ad/telemetry/malware blocking lists pihole uses without having to configure dns on everything.

Those piholes also keep lists/records in sync using Gravity-Sync. Should I change ad lists or add/remove lan dns records, I don’t have to do it on both.

I use Control-D, both on Android, through DNS over TLS, and at the router level, so that I’m protected from ads and malware, no matter whether I’m on cellular data or on Wi-Fi.

PiHole with unbound (it’s its own recursive DNS resolver so you don’t depend on Cloudflare, Quad9 and others) set on my local network DHCP, plus AdGuard’s DNS Proxy to use PiHole outside my home on my phone through DNS over TLS.

DHCP at the router that gives out these two filtered DNS servers from AdGuard:

• 94.140.14.14
• 94.140.15.15

Mullvad’s DNS servers at the router level.

/etc/unwind.conf

block list "/var/db/unwind_blocklist"
forwarder { X.X.X.X port X DoT X.X.X.X port X DoT }
preference { DoT }

unwind_blocklist is generated with this script I wrote:

#!/bin/sh
# Blocklists for unwind(8)

blocklist=/var/db/unwind_blocklist
[ ! -f $blocklist ] && \
        (umask 117; touch $blocklist && chgrp _unwind $blocklist)

Pi-Hole using upstream Quad9 and Cloudflare, managed router redirect/blocking everything to Pi-Hole or no mans land, NextDNS out of the house for mobile devices or on WiFi I don’t control.

When using the network-wide VPN configuration of my firewall, I also use OPNSense to enforce that all devices connect to my self-hosted Pi-Hole, including redirecting DNS packets that are sent to DNS servers other than my Pi-Hole IP. There’s a pretty cool guide for this: https://forum.opnsense.org/index.php?topic=9245.0

When running a VPN client on a device, I just use the VPN to manage DNS settings.
Both Mullvad and IVPN have very solid DNS settings within their desktop clients. Proton VPN unfortunately lacks behind in this regard. That’s why I never use any Proton VPN clients on desktop, and rely on OPNSense, if I want to use Proton.

I use a mix: I’ve got hardcoded hosts files, default third party DNS provider, DoH providers (different for each browser), a PiHole, and a VPN-based DNS resolver that I can run on a per-app basis.

This way, I don’t trust a single provider to handle all my DNS traffic.

I use several providers as upstream for Adguard Home where my blocklists, regex blocks and DNS rewrites are. Via DNS-over-TLS URL for Android phones or DHCP with the IP of the DNS-server they get directed to it.

TrackerControl on android, pihole at home.

I use portmaster

Can you elaborate more? Do you want controlled lookups, or just one of the public ad-removing providers?

I use NextDNS. I use it network wide on my home internet and also have it installed on all my devices.

AdGuard Pro which runs a local DNS server.
