Bunny DNS IBM Cloud Classic (SoftLayer) DNS

Migrate DNS from Bunny to SoftLayer.

8 record types move as they are. 2 things work differently at SoftLayer, 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
  • PTR

Apex CNAMEs need a different shape

SoftLayer 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.

A typical Bunny zone at SoftLayer

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

Bunny SoftLayer

  • ExactA@

    192.0.2.70

  • ExactAAAA@

    2001:db8::70

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

    "v=spf1 include:_spf.example.net -all"

  • UnsupportedCAA@

    Not migrated

    SoftLayer doesn't support CAA records through its API.

  • 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 SoftLayer

    Connect SoftLayer (Classic infrastructure username + API key). 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 SoftLayer

    We snapshot the SoftLayer zone, write in batches, and leave Bunny untouched.

  5. 5

    Verify

    We query SoftLayer'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 SoftLayer

  • Domains must already exist in the IBM Cloud classic DNS console. We can't create them.
  • Only A, AAAA, CNAME, MX, NS, PTR, SPF, SRV and TXT records are supported, so CAA records can't be migrated here.
  • The minimum TTL is 60 seconds, and the DNSControl provider for SoftLayer is unmaintained, so treat this integration with extra care.

Access we need: A classic infrastructure user with the Manage DNS permission for both preview and apply.

Questions

Will there be downtime moving from Bunny to SoftLayer?

Not if both providers serve the same answers during the switch. The records are copied to SoftLayer 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 SoftLayer and publish its new DS record. The cutover plan walks you through each step.
