I have a pi hole in my network and I set it as my primary DNS server, and my router (a Mikrotik) as secondary. DHCP sets the DNS servers as pihole, mikrotik in this exact order and I want to keep it that way. I know systemd-resolved uses some algorithm to set the fastest dns as current server, but I don’t want/need that. Is there some way to do configure it to just let it be?
I’m running Fedora 40.
If you set the Microtik as Pihole’s upstream server, you should get both Microtik’s local domains and ad blocking.
You may need to disable DNSSEC validation to get it to work if you use a real domain for local records, though.
