Global DNS Zones
The Global DNS Zones page is the cross-server view of every DNS zone served by the hub cluster, together with where each zone originates.
Overview
URL: /admin/hub/dns-zones - under Cluster → Global DNS Zones
Every zone served by the hub cluster, with its origin across the fleet.
Use Filter by zone or source to search, and Refresh to re-read the current state.
Cluster members
Every server feeding the hub PowerDNS, with its sync status.
| Column | Description |
|---|---|
| Server | Member name and address (for example the hub Staging Fleet, or a node named testing). |
| Type | Member role, such as hub. |
| Status | Sync state, such as active. |
| Zones | Number of zones the member contributes. |
| How | How the member feeds the cluster, such as local (primary). |
| Last sync | Time of the last successful sync. |
| Error | The last sync error, if any. |
Zones
Below the members, every zone is listed with its provenance:
| Column | Description |
|---|---|
| Zone | The DNS zone (domain). |
| Type | Zone type, such as MASTER. |
| Source | Where the zone comes from, such as Hub (local) or an external source. |
| How obtained | For example, Local master. |
| Transfer Master | The transfer master for slaved zones, if any. |
| Check serial | Row action that checks the zone's current serial. |
Export and import a zone
Export
Export zone downloads any served zone as a standard BIND zone file, named <domain>.zone. The records are read back from the hub's own PowerDNS, so a mirrored zone exports exactly what the hub is serving rather than what a source once sent.
Import
Import zone loads a BIND zone file into a hub-local zone. The form offers:
- BIND zone file (required) - up to 512 KB. A standard BIND zone file works, for example an export from cPanel, Plesk or another AdminBolt server.
- Import mode (required) - Add to existing records, where duplicates are skipped, or Replace existing records, where the SOA record is kept and the NS records are kept when the file has none. Add is the default.
- Preview - shown as soon as a file is selected. It lists what would be applied, and every line that cannot be applied with the reason: an unsupported record type, a record outside the zone, or a malformed line. TTLs outside the
60to86400range are clamped, with a warning.
Warning: Import is available only for zones hosted on this panel. A mirrored zone, whether it comes from a node or an external source, cannot be imported into: its source stays authoritative and the next synchronisation would overwrite whatever you imported. Change such a zone at its source instead.
