IONOS DNS Pro review
A low-cost secondary DNS add-on for organizations already using IONOS.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
IONOS DNS Pro is a paid DNS management add-on for domain owners, businesses, and organizations that want a secondary authoritative DNS provider. It transfers zone data from a primary DNS server over AXFR and is managed through the IONOS account. The service is available through the web and API, making it suitable for small, mid-market, and enterprise teams that need additional DNS redundancy, availability, and administrative control without adopting a separate provider for core DNS operations.
The published plan structure is simple: DNS Pro costs $2.50 per month on monthly billing. The plan includes Secondary DNS, DNSSEC, Premium Anycast, and DNS backup and restore. It also provides DNS zone templates, domain and DNS settings management through the API, and account-based DNS administration. The published price is promotional for the first 12 months, with the stated starting price using the subsequent regular price. There is no free plan, so the service is aimed at organizations with a paid DNS requirement.
Its strongest fit is for IONOS customers that want secondary DNS, AXFR transfers, backup and restore, and API-based management in one service. Support is available 24/7 through email, chat, and phone, with documentation also provided. DNSSEC is documented for compatible domains, but it must be used with default IONOS nameservers and with Secondary DNS deactivated. That condition matters for teams planning to combine DNSSEC and secondary service in the same configuration. Choose DNS Pro for affordable managed secondary DNS within the IONOS ecosystem; consider another option if an IONOS contract or that DNSSEC setup requirement does not suit your environment.
