+# PowerDNS Notes
+
+## v1 Design
+- Authoritative server: powerdns/pdns-auth (Docker)
+- Backend: sqlite3 in PDNS_DATA_DIR
+- API enabled and published to localhost only
+
+## Production Hardening
+- Run behind firewall; restrict UDP/TCP 53 to known resolvers or public as needed
+- Keep API bound to localhost
+- Consider a second NS (ns2) on a separate node/provider for resilience
+- Back up PDNS_DATA_DIR using backup-sovereign
