After upgrading the Mac client 0.68.3 -> 0.71.3 (matching mgmt) and clearing
its NetBird resolver cache (netbird service restart), the managed-zone
deletion works: with 0 managed-zone records, the Mac resolves all
hubris.network names by forwarding to Technitium (192.168.8.2). iPhone
confirmed on cellular (no LAN path -> proves mesh-forward).
The first deletion "failure" was a misdiagnosis: the old 0.68.3 resolver
cache held stale answers and wouldn't clear on down/up (needs daemon
restart); the Mac's dual LAN+mesh paths muddied it. A direct
dig @100.122.255.254 of an unsynced name had shown forwarding working.
Done:
- Deleted all 23 NetBird managed-zone A-records.
- Removed the */10 dns-sync cron. Kept /opt/dns-sync/sync.py + token +
pre-deletion backup as an emergency-restore tool only.
End state: Technitium is the single DNS source. Mesh peers forward to it
(Core route -> 192.168.8.0/24); LAN/household query it directly. No replica,
no sync. Requires mesh clients on 0.71.x+.
Docs: dns.md + 107-dns.md updated to single-source; subdomain recipe no
longer references the sync.
