In a connected world, as Internet users expect seamless and secure online experiences, DNS has become more difficult and complex to manage than ever before. The emergence of IoT devices and online threats leave businesses struggling to find the correct DNS strategy for their IT needs. Having the experience and DNS know-it-all in-house is nearly impossible, let alone having the dedicated resources to correctly manage and implement a sound strategy to meet today’s Internet demands.

Neustar UltraDNS is an enterprise grade, cloud-based authoritative DNS service that securely delivers fast and accurate query responses to websites and other vital online assets. Whether you’re looking for a Primary or Secondary DNS solution, Neustar UltraDNS offers customizable packages to fit any organization’s DNS needs.

Our trusted authoritative network uses BGP and IP Anycast routing schemes to manage over 33 billion global queries per day. The UltraDNS nodes are co-located with Neustar’s recursive and top-level-domain (TLD) servers, providing near-zero latency responses amongst them and instant cache updates for the zones that Neustar hosts.


Ensure that your website and other online assets are always available. Backed by our 100% uptime guarantee and industry leading SLAs, UltraDNS offers a global platform that is highly redundant and operated with 30 non-virtualized nodes across 6 continents.



Unlike BIND based DNS services, our network is engineered on a proprietary non-open source platform that is less vulnerable to online threats. Nameserver segmentation and DNSSEC support add an additional layer of protection that allows effective DDoS protection and prevents malicious activity. Learn How you Can Strengthen Your DNS Security.

Advanced DNS Traffic Management Services

SiteBacker — Monitoring & Failover

As web-based operations become increasingly mission-critical, a server failure can massively disrupt your business and bottom line. Avoid the need for deploying expensive monitoring and failover solutions by implementing SiteBacker: a monitoring and failover service.

Traffic Controller — Weighted Load Balancing

Gain the ability to define load balancing configurations (weighted or round robin) without the need for in-house hardware costs or management. Traffic Controller also includes SiteBacker, which allows the ability to dynamically modify weighted traffic away from unresponsive servers.


Directional DNS — Geolocation Based Routing

Improve website performance and user experience by sending your visitors to specific servers based on their geographic locations, while also protecting your network by restricting traffic from unwanted regions, countries, or provinces.

Basic Traffic Management

All packages include a basic level of traffic management options: Simple Monitoring, Simple Failover, and Simple Load Balancing, which provide an added layer of performance and redundancy at no additional cost.
