Supported provider
IONOS DNS, in the same place as everything else.
Does DNSMentor support IONOS?
Yes. DNSMentor manages IONOS DNS through its API, showing its zones alongside the other 25 supported providers in a single estate view. Every IONOS change goes through the same 56 pre-flight checks, approval policy, independent verification and tamper-evident audit trail as every other provider.
Connecting IONOS
- Create the credential in IONOS IONOS Developer portal → https://developer.hosting.ionos.com/keys → your key. The public prefix is the shorter of the two values and is safe to store in the clear; it is how you identify this key later when you want to revoke it.
- Add the connection in DNSMentor Go to Admin → Providers & API keys, choose IONOS, and paste the credential. DNSMentor stores it encrypted and strips it from every log and export.
- Sync the estate DNSMentor discovers every zone the IONOS account holds and imports every record in them. This is a read operation — nothing is written to any zone.
- Group by client and start working Assign the imported domains to client portfolios, and the estate view, health scoring, checks and audit trail apply from that point on.
What IONOS asks you for
The exact fields DNSMentor needs, and where in IONOS to create them. Every secret is encrypted at rest and stripped by name from logs, exports and the audit trail.
Public Prefix not secret IONOS Developer portal → https://developer.hosting.ionos.com/keys → your key. The public prefix is the shorter of the two values and is safe to store in the clear; it is how you identify this key later when you want to revoke it.
API Secret secret The second value shown when the key is created at https://developer.hosting.ionos.com/keys → Create New Key. It is displayed once and cannot be retrieved afterwards — if it has been lost, create a new key and delete the old one. The key is account-wide: it can read and change DNS for every domain in the IONOS contract, and IONOS offers no read-only or per-zone variant.
The sharp edge in IONOS's API
Every provider API has one behaviour that catches integrations out. This is IONOS's, and DNSMentor's adapter is written around it — the sort of thing you would otherwise discover during a migration.
What you get on top of the IONOS console
One estate, not one provider
IONOS zones sit beside every other provider your clients came with, grouped by the client who pays for them and searchable in one place.
56 checks before apply
The IONOS console will accept a second SPF record or an MX pointing at an address without comment. DNSMentor will not.
Approval and audit
A second pair of eyes where policy requires it, and a hash-chained record of who changed what — neither of which a provider console offers.
IONOS questions
Can I manage IONOS DNS alongside my other providers?
Yes. DNSMentor connects IONOS through its API and shows its zones in the same estate view as every other provider you connect — 26 are supported in total. Your engineers work in one interface instead of switching between provider portals, and the same checks, approval policy and audit trail apply regardless of which provider a domain happens to be with.
What credentials does DNSMentor need for IONOS?
DNSMentor needs Public Prefix, API Secret for IONOS. IONOS Developer portal → https://developer.hosting.ionos.com/keys → your key. The public prefix is the shorter of the two values and is safe to store in the clear; it is how you identify this key later when you want to revoke it.
Does DNSMentor move my zones away from IONOS?
No. Your zones stay hosted at IONOS and remain authoritative there. DNSMentor reads and writes through the IONOS API, so nothing about your resolution path changes, and if you stop using DNSMentor the zones carry on exactly as they are.
Does DNSMentor validate IONOS changes before applying them?
Yes. All 56 checks run against the zone as it would exist after the change, whichever provider hosts it. The change is then simulated, routed for approval if policy requires it, written through the IONOS API after re-reading live state, and independently verified in public DNS afterwards.
Other providers DNSMentor manages
Connect IONOS in about five minutes.
Paste one credential, sync, and see every zone in that account. It is a read operation — nothing is written until somebody presses apply.
No card. No trial clock. UK-hosted, and we will tell you which providers we have actually proven before you ask.
