CentralNic Reseller deSEC

Migrate DNS from CentralNic to deSEC.

17 record types move as they are. 2 things work differently at deSEC, 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
  • DNAME
  • NAPTR
  • SSHFP
  • TLSA
  • SMIMEA
  • LOC
  • SVCB
  • DHCID

Alias records are converted

CentralNic alias records become CNAMEs below the apex. At the apex they need static addresses, and the preview shows which ones.

TTLs below 3600s are raised

deSEC's minimum TTL is 3600 seconds. Shorter TTLs are raised to 3600s and shown as translated.

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

How the move works

  1. 1

    Connect CentralNic

    Connect CentralNic with read-only access (Reseller (or sub-user) login + password over the HTTPS gateway).

  2. 2

    Connect deSEC

    Connect deSEC (API token). 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 deSEC

    We snapshot the deSEC zone, write in batches, and leave CentralNic untouched.

  5. 5

    Verify

    We query deSEC'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 CentralNic

  • Creating a KeyDNS zone can incur a charge on your reseller account.
  • ALIAS records only work on unsigned zones; they can't be used with DNSSEC signing.
  • Web and mail forwards are separate objects in the API and aren't migrated as DNS records.

Access we need: A sub-user allowed QueryDNSZoneList, QueryDNSZoneRRList and StatusDNSZone for the preview; ModifyDNSZone (and AddDNSZone to create zones) to apply.

Good to know about deSEC

  • The minimum TTL is 3600 seconds for most domains (deSEC sets it per domain) and the maximum is 86400.
  • ALIAS/ANAME records and apex CNAMEs aren't supported; use A/AAAA or HTTPS records at the apex.
  • Every zone is DNSSEC-signed automatically. Give the DS records to your registrar to complete the chain.

Access we need: Any token can read all RRsets. Applying needs write permission on the RRsets (token policies can restrict it); creating zones needs perm_create_domain.

Questions

Will there be downtime moving from CentralNic to deSEC?

Not if both providers serve the same answers during the switch. The records are copied to deSEC 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 CentralNic?

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