Cloudflare DNS Realtime Register

Migrate DNS from Cloudflare to Realtime Register.

15 record types move as they are. 6 things work differently at Realtime Register, and the preview shows exactly which of your records they affect.

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

What works differently

Generated from the same provider capability data the migration engine uses.

Proxied records lose the CDN

Realtime Register 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

Realtime Register doesn't allow a CNAME at the zone apex, but its ALIAS record does the same job. We convert them automatically.

"Auto" TTLs get a real value

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

Realtime Register rewrites the whole host list

Every write to Realtime Register's API replaces all records. We read, merge and write once, so records outside the migration survive.

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.

How the move works

  1. 1

    Connect Cloudflare

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

  2. 2

    Connect Realtime Register

    Connect Realtime Register (API key (Authorization: ApiKey)). Write access is only used when you apply.

  3. 3

    Review the preview

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

  4. 4

    Apply to Realtime Register

    We snapshot the Realtime Register zone, write in batches, and leave Cloudflare untouched.

  5. 5

    Verify

    We query Realtime Register's own nameservers for every record and compare the answers before you switch.

  6. 6

    Switch nameservers

    Lower TTLs a day or two ahead, remove any DS record if DNSSEC is on, then point the domain at the new nameservers at your registrar.

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 Realtime Register

  • Every change rewrites the zone's full custom record list in one request; records we don't manage (such as MBOXFW and HINFO) are sent back unchanged.
  • Basic and Premium DNS are separate services with separate zones; the connection works with one of them at a time.
  • Zones linked to a DNS template also receive the template's records, which are managed on the template, not per zone.

Access we need: An API user with VIEW_DNS_ZONE for the preview; CREATE_DNS_ZONE and UPDATE_DNS_ZONE to apply.

Questions

Will there be downtime moving from Cloudflare to Realtime Register?

Not if both providers serve the same answers during the switch. The records are copied to Realtime Register 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 Realtime Register 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 Realtime Register can't proxy traffic. The preview lists every proxied record and the IP it would expose.
