Cloudflare DNS NexDNS

Migrate DNS from Cloudflare to NexDNS.

11 record types move as they are. 5 things work differently at NexDNS, 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

NexDNS 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

NexDNS 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 NexDNS'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 NexDNS

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

Cloudflare NexDNS

  • TranslatedALIAS@

    app.example-host.net.

    Apex CNAME stored as a NexDNS ALIAS record.

  • 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 NexDNS

    Connect NexDNS (API key (Bearer, nxd_ prefix)). 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 NexDNS

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

  5. 5

    Verify

    We query NexDNS'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 NexDNS

  • The SOA record and the apex NS records are managed by NexDNS and can't be changed, so dual-hosting a zone with a second provider isn't possible.
  • Records are written one value per request against a per-account rate limit, so large zones take a while to apply.
  • Only A, AAAA, CNAME, MX, TXT, NS, SRV, CAA, PTR, ALIAS, DNAME, DS and TLSA are supported; ALIAS is the way to point the apex at a hostname.

Access we need: zones.read and records.read for the preview; add records.write to apply and zones.write to create zones or switch DNSSEC. API access needs a Pro plan or higher.

Questions

Will there be downtime moving from Cloudflare to NexDNS?

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