Our verdict on UltraDNS

Organizations operating distributed online infrastructure can use UltraDNS to host and manage authoritative DNS zones. DigiCert’s service covers primary, secondary, and alias zones, with administration through a web portal or REST API. DNSSEC signing and key management, zone transfers, traffic steering, health monitoring, and security controls place it toward teams that need operational control over DNS rather than only basic record hosting.

Routing is a central part of the offer. UltraDNS supports geographic and source-IP steering, weighted traffic control, and load balancing, alongside health monitoring with automated failover. DNS health and configuration checks provide another layer for overseeing zone health. These capabilities suit environments that need to direct traffic using more than a single fixed destination and respond to health conditions. Buyers with straightforward DNS needs may not benefit from this range of controls and could prefer a simpler service.

According to DigiCert’s pricing description, UltraDNS packages are customizable around domains, DNS queries, users, and advanced features, with pricing handled through sales rather than a public self-service price. The published material also does not provide a public zone allowance, so teams comparing costs will need to discuss their expected usage and requirements with DigiCert. Consider UltraDNS when advanced routing, DNSSEC, failover, and API-based management matter; it is less suited to buyers who need transparent, self-serve pricing before evaluating a provider.
