Redundant & Secondary DNS

Achieve better business continuity and protect against malicious attacks.

Managed Icon

Although modern managed DNS services are designed for high availability, they are not immune from outages. Outages can result from denial of service attacks, failures in critical network infrastructure, or configuration errors. The result of a DNS outage is that your applications and content are no longer available to users.

DNS redundancy is now a must have for many enterprises, but deploying a redundant DNS infrastructure often involves trade-offs in cost, manageability, and performance. You might find yourself cobbling together management of different vendors and settling for minimally viable, common features shared between the vendors. NS1 eliminates the need to settle for something less, giving you all of our advanced routing and management across both its managed and dedicated DNS. NS1 offers several redundant DNS options designed to meet the needs of organizations of all sizes.

What's more, only NS1 can combine managed and dedicated DNS networks controlled with a single pane of glass to reduce the headaches of two DNS providers and give you all NS1’s advanced traffic routing capabilities.


Dedicated DNS

With Dedicated DNS, you get a DNS service deployed on a separate network and servers from your NS1 Managed DNS. Dedicated is deployed on anycasted infrastructure and it is provisioned to meet the your load and geographic distribution requirements. NS1 takes care of design, deployment, and management. Your Dedicated deployment is not shared with any other customers, so it is not exposed to the effects of attacks targeting other customers on the NS1 Managed service or attacks on the service itself.

Dedicated DNS gives you all of the advanced traffic management capabilities of NS1 Managed DNS. You eliminate multi-vendor gymnastics because you can manage both DNS networks through one pane of glass.  There are no record synchronization issues and you get complete meta data and filter chain capabilities on all your DNS points of presence. No other dual DNS system is as simple to manage and yet requires no trade-offs in traffic management.

Redundant, or Secondary DNS with Another DNS Provider

Many NS1 customers use our service in conjunction with another DNS provider. Because different providers implement DNS traffic management in different ways, there can be complexities in ensuring records are fully synchronized in a dual provider set up. A dual provider approach is ideal for customers that are not heavy users of complex DNS traffic management algorithms.

NS1 is experienced in working with customers to ensure there are no record synchronization issues and is happy to provide the assistance needed to establish dual provider redundancy. We also support toolkits like OctoDNS and Terraform to make working with multiple DNS providers as easy as possible.
