Cloudflare DNS BIND zone file

Export Cloudflare DNS to a zone file.

18 record types move as they are. 5 things work differently at Zone file, and the preview shows exactly which of your records they affect.

Free preview. Read-only. Nothing changes until you apply.

Proxied records lose the CDN

Zone file has no equivalent of Cloudflare's proxy. Proxied records move as plain records pointing at your origin, which exposes the origin IP. Put a CDN in front before cutting over if that matters.

Apex CNAMEs need a different shape

Zone file doesn't allow a CNAME at the apex and has no alias record for external hostnames. These become static A/AAAA records, which don't follow the target if its IPs change.

"Auto" TTLs get a real value

Cloudflare's automatic TTL has no equivalent, so those records get Zone file's default of 3600s.

Domains registered at Cloudflare must transfer out

Cloudflare Registrar only allows Cloudflare's nameservers. If the domain is registered there, transfer it to another registrar before switching.

A typical Cloudflare zone at Zone file

Example records for example.com. Open any flagged row to read why it changed.

Cloudflare Zone file

  • UnsupportedCNAME@

    Not migrated

    @ is a CNAME at the zone apex. Zone file doesn't allow that, and app.example-host.net isn't a target it can alias.

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

    "v=spf1 include:_spf.example.net -all"

  • ExactCAA@

    0 issue "letsencrypt.org"

  • ExactTXT_dmarc

    "v=DMARC1; p=reject; rua=mailto:dmarc@example.com"

  • ExactSRV_sip._tls

    100 1 443 sip.example.net.

  • ExactAmail

    203.0.113.25

  • ReviewAshop

    203.0.113.10

    TTL was "auto". Set to 3600s.

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Cloudflare

    Connect Cloudflare with read-only access (Scoped API token).

  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 Cloudflare

  • Proxied (orange-cloud) records hide the origin IP. Moving them to another provider sends traffic straight to the origin.
  • Apex CNAMEs are flattened by Cloudflare. Other providers need an ALIAS record or static A/AAAA records instead.
  • Cloudflare Registrar only allows Cloudflare nameservers, so domains registered there must be transferred out first.

Access we need: Zone → DNS → Read for the preview, Zone → DNS → Edit 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 Cloudflare 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 Cloudflare?

No. We never write to Cloudflare. 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.

What happens to Cloudflare proxied records?

They move as ordinary records pointing at your origin server, because Zone file can't proxy traffic. The preview lists every proxied record and the IP it would expose.
