Good to know about Azure DNS

  • Azure alias records point at Azure resource IDs, which don't exist outside Azure.
  • Apex CNAMEs are not allowed. Use an alias record to an Azure resource or A/AAAA records.

Access we need: Reader on the DNS zone for the preview, DNS Zone Contributor to apply.

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 Azure DNS 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 Azure DNS?

No. We never write to Azure DNS. 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.
