I have a service running on a static IP within my LAN and PiHole specifies a domain name for that IP address. For example, my.server.com === 192.168.1.10. Prior to Big Sur, this worked fine. Now, it keeps reverting to whatever global DNS records specify instead of the address provided by PiHole. If I clear the DNS cache with sudo killall -HUP mDNSResponder the name will resolve to the desired IP address for a very short time (less than a minute or two) and then revert to the global records. Short of using /etc/hosts how can I get Big Sur to respect PiHole's DNS?
