Alias records are converted

PowerDNS alias records become CNAMEs below the apex. At the apex they need static addresses, and the preview shows which ones.

How the move works

  1. 1

    Connect PowerDNS

    Connect PowerDNS with read-only access (API URL + API key (X-API-Key) + server ID).

  2. 2

    Connect Zone file

    Choose zone file as the destination. Nothing is written anywhere.

  3. 3

    Review the preview

    Check every record marked Review or Unsupported. Each one explains what changes and why.

  4. 4

    Download the zone file

    Download a normalized RFC 1035 zone file ready to import anywhere.

Good to know about PowerDNS

  • We only connect to public HTTPS addresses: expose the PowerDNS webserver through a reverse proxy with TLS and allow-list our egress IPs; private or internal addresses are refused.
  • ALIAS records only resolve if expand-alias and a resolver are configured on the server, and DNAME needs dname-processing.
  • Disabled records are not imported, and an RRset we update is replaced as a whole, so disabled entries inside it are dropped.

Access we need: The PowerDNS API key grants full read/write access to every zone on the server; there is no read-only key. Restrict it with webserver-allow-from.

Good to know about Zone file

  • Zone files can't express provider features like proxying, alias records or routing policies.

Access we need: No credentials. Everything stays in your browser until you choose to save it.

Questions

Will there be downtime moving from PowerDNS to Zone file?

Not if both providers serve the same answers during the switch. The records are copied to Zone file and verified before you change nameservers, so resolvers get the same answer from either side while caches expire.

Do I have to delete anything at PowerDNS?

No. We never write to PowerDNS. Keep the old zone for a week after cutover so you can switch back instantly if anything looks wrong.

What about DNSSEC?

If DNSSEC is on, remove the DS record at your registrar and wait for it to expire before switching nameservers. Then enable DNSSEC at Zone file and publish its new DS record. The cutover plan walks you through each step.
