UltraRecursive DNS
Get a faster, safer and more reliable Internet experience with Neustar UltraRecursive, a cloud-based Recursive DNS service.
Owning a trusted recursive DNS service is crucial in our modern connected world. The DNS perimeter has drastically expanded as global workforces now utilize multiple devices to connect to the Internet – increasing your network’s load and exposure. This expansion not only increases performance demands, but also limits your visibility into the threats that are targeting and infecting your networks, ultimately putting your organization in harm’s way. Despite your current safety measures and security provisions, malware still bypasses network defenses, costing you more time and money on cleanups – as well as hindering network performance.
Neustar UltraRecursive DNS is a cost effective enterprise grade, cloud-based recursive DNS service that delivers fast and reliable access to vital online applications with built-in security and threat intelligence.
Quickly resolves queries through a highly reliable, global DNS infrastructure. The UltraRecursive nodes are co-located with Neustar’s authoritative and top-level-domain (TLD) servers, providing near-zero latency responses and instant cache updates for the zones that Neustar hosts.
Our recursive DNS service stops threats at the first point of contact and blocks malware before it reaches networks or endpoints by using Neustar and third-party threat intelligence feeds.
The recursive DNS solution mitigates threats by preventing access to malicious websites known for malware, phishing, spyware and bots. Blocks unwanted and inappropriate content by using pre-defined, category-based web filtering, along with custom white/black lists.
Cloud-based, managed solution adds an extra layer of performance and security without the need for appliances, installations or additional configurations; saving time and money – all with the added benefits of a web-based portal, detailed reporting and industry leading SLAs.
Built-in DDoS protection to defend against attacks towards UltraRecursive and to ensure that your DNS does not become a source for future DDoS attacks against others.
Provided free of charge, Public DNS enables users, families, and small businesses to experience a much more reliable, faster and safer online experience. Simply change your DNS settings and experience the Internet like never before.
