RFC2136 dynamic-DNS updater. Watches a records file (inotify) and new interface addresses and pushes TSIG-signed updates to BIND per zone, sending only the delta. Native miekg/dns (structured per-zone RCODEs), local status API + facter fact, systemd unit, nfpm RPM, Woodpecker CI. Replaces the puppet dns-update shell script; keeps the same records-file and TSIG-key contract.
