- Auto plugin loads zones-prepared/*.zone (regex zone-name extraction) - scripts/prepare-zones.sh transforms raw Vultr exports: * synthesizes SOA (omitted by Vultr; CoreDNS requires it) * prepends @ to leading-TAB apex lines to disambiguate owner inheritance * dot-terminates NS/MX/CNAME rdata so $ORIGIN doesn't double-suffix - DNS_PORT defaults to 1053 (5353=avahi, 53=libvirt dnsmasq on this host) - Forwards non-authoritative queries to 1.1.1.1/1.0.0.1/9.9.9.9 - Makefile targets: prep, up, down, reload, test, logs - 91 zones loaded
