Zone metadata - PowerDNS Web UI

PowerDNS zone metadata controls behavior that is not represented by ordinary DNS records. PowerDNS Web UI exposes common metadata used for zone transfers and SOA serial handling.

Supported metadata

Metadata	Purpose
`ALLOW-AXFR-FROM`	IP addresses or ranges allowed to AXFR this zone
`ALSO-NOTIFY`	Extra nameservers or IPs to notify after zone changes
`AXFR-SOURCE`	Source address PowerDNS uses for outgoing AXFR requests
`SOA-EDIT`	SOA serial modification policy for zone changes
`SOA-EDIT-API`	SOA serial modification policy for API changes

ALLOW-AXFR-FROM

Use ALLOW-AXFR-FROM on a primary zone to permit secondaries to transfer it. Example values:

192.0.2.10
2001:db8::10

SOA serial behavior

SOA-EDIT and SOA-EDIT-API control how PowerDNS adjusts SOA serial numbers after zone changes. Choose a policy that matches your operational model. If your secondaries depend on serial increases, make sure API edits update the serial consistently.

ALSO-NOTIFY

Use ALSO-NOTIFY when you want PowerDNS to send notifications to additional secondaries beyond the default NS-derived targets. Enter one destination per line, for example:

192.0.2.53
2001:db8::53
ns-secondary.example.net

Autoprimaries

Autoprimaries let PowerDNS automatically provision secondary zones when a trusted primary sends a notification. PowerDNS Web UI can list, create, and delete autoprimary entries through the PowerDNS API.
