Bunny DNS deSEC

Migrate DNS from Bunny to deSEC.

12 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
  • HTTPS
  • SVCB
  • TLSA

Apex CNAMEs need a different shape

deSEC 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.

TTLs below 3600s are raised

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

A typical Bunny zone at deSEC

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

Bunny deSEC

  • TranslatedA@

    192.0.2.70

    TTL 300s is outside the allowed range. Set to 3600s.

  • TranslatedAAAA@

    2001:db8::70

    TTL 300s is outside the allowed range. Set to 3600s.

  • 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.

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Bunny

    Connect Bunny with read-only access (Account API key).

  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 Bunny 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 Bunny

  • Pull Zone, Script and Flatten records, and disabled records, aren't migrated. Redirect records are read as URL redirects to recreate by hand.
  • Records that use smart routing (latency or geolocation) or CDN acceleration are flagged and never changed by us.
  • An apex CNAME is flattened by Bunny, so it can point at any hostname.

Access we need: The account API key has full access. There is no read-only key, so rotate it after the migration.

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 Bunny 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 Bunny?

No. We never write to Bunny. 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.
