What Dun can do
Each product below is something you can turn on. The examples are real prompts you can type in a chat thread.
IONOS account
IONOS' DNS API lets DunOps list your DNS zones, preview existing records, and apply approved DNS changes. Connect with an IONOS DNS API key.

"Authentication failed"
Cause: The API key/token was revoked or the IP allow-list at IONOS doesn't include Dun's egress IP.
Fix: Regenerate the key in IONOS, and if IONOS enforces IP allow-listing, add Dun's egress IP (Settings → Providers shows it) before saving.
"Record already exists"
Cause: A conflicting record (same name + type) is already present.
Fix: Ask Dun to update the existing record instead of adding a new one — it will show the before/after diff.
