ClouDNS hosting.de

Migrate DNS from ClouDNS to hosting.de.

13 record types move as they are. 2 things work differently at hosting.de, 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.

Moves as-is

  • A
  • AAAA
  • CNAME
  • MX
  • TXT
  • NS
  • SRV
  • CAA
  • PTR
  • ALIAS
  • TLSA
  • SSHFP
  • DS

Routing policies are flattened

hosting.de has no routing policies. Weighted, geo and latency sets collapse into one set of answers, and failover keeps only the primary. Each one is flagged for review.

How the move works

  1. 1

    Connect ClouDNS

    Connect ClouDNS with read-only access (API user auth ID (or sub-user ID/name) + password).

  2. 2

    Connect hosting.de

    Connect hosting.de (API key (authToken), optional sub-account ID). 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 hosting.de

    We snapshot the hosting.de zone, write in batches, and leave ClouDNS untouched.

  5. 5

    Verify

    We query hosting.de'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 ClouDNS

  • TTLs must be one of ClouDNS's fixed values (60, 300, 900, 1800, 3600, 21600 … 2592000); other TTLs are rounded up.
  • Web redirects (CLOUDNS_WR) are ClouDNS-only and are written as plain 301 redirects without frame options.
  • The API is rate limited to about 20 requests per second per IP, so large zones apply record by record and take a while.

Access we need: A read-only API sub-user with the zones delegated is enough for the preview; applying needs a read-and-write sub-user or a main API user.

Good to know about hosting.de

  • Record changes are processed asynchronously; while a zone is blocked by a running job we retry automatically.
  • TTLs must be between 60 seconds and one year.
  • Automatic DNSSEC publishes keys to the registry only for domains registered at hosting.de.

Access we need: An API key with DNS zone/record read rights for the preview; record edit (and zone create) rights to apply.

Questions

Will there be downtime moving from ClouDNS to hosting.de?

Not if both providers serve the same answers during the switch. The records are copied to hosting.de 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 ClouDNS?

No. We never write to ClouDNS. 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 hosting.de and publish its new DS record. The cutover plan walks you through each step.
