I think I did not blog about it, but I switched back to a self-hosted AdGuard Home instance quite some time ago from NextDNS. To reduce my number of subscriptions, but also to increase my control over important infrastructure I use.

As upstreams in AdGuard Home, I used DNS4EU, Mullvad, and Quad9.

However, today, I switched to a self-hosted instance of PowerDNS Recursor. So no more reliance on third-party DNS resolvers, except the root and authoritative nameservers.

I try it with AdGuard Home first, as I later also want to set up a second PowerDNS Recursor instance on my mail server to make use of some more spam protection features.

Let’s see if any problems appear. When yes, “it was DNS”! 😅
