Here's a data point. My Void Linux physical machine Daily Driver Desktop (DDD) has both unbound and dnsmasq installed, and if there's any interference, I'm not aware of it. ===================================================== [slitt@mydesk nq]$ time dig @192.168.0.102 masterblaster.com ; <<>> DiG 9.16.22 <<>> @192.168.0.102 masterblaster.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 25686 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 1232 ;; QUESTION SECTION: ;masterblaster.com.
