Neustar UltraDNS

Cloud-based Authoritative DNS for Faster, Safer and Accurate Query Resolution


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 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.

Performance - our trusted authoritative network uses BGP and IP Anycast routing to manage over 37 billion global authoritative DNS 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.

Availability - 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.

Security - unlike BIND based DNS services, our primary DNS 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 to effectively mitigate malicious activity.

DDoS Protection - Built-in DNS DDoS protection with local mitigation that quickly defends against attacks towards the UltraDNS network and ensures that uptime and availability aren’t compromised.

DNS Shield™ - enhancing both performance and security, DNS Shield is a global network of private connections between UltraDNS and its partners that is independent of public Internet networks. By implementing these private connections, UltraDNS is able to minimize the security risks of DDoS attacks & DNS spoofing while allowing for lower latency and better reliability for query responses.

Comprehensive SLA - covering query availability, query resolution, change propagation, query latency and customer support.
