I’ve been on the Adguard home train after getting my new Proxmox box and trying it out as a replacement for PiHole. It turns out, it’s great! A ton of great features that make PiHole look quite ancient (which I suppose it is).

I ran it as a daemon to sync my primary every two hours and now I’ve got a secondary DNS server specified in my router!
