DNS Traffic Management

Rethink DNS-Based Traffic Management with NS1’s Filter Chain + Pulsar

NS1’s next-generation DNS lets you easily configure simple to complex, customized traffic management algorithms perfectly suited to your application and network.

Hone your traffic rules using dozens of configurable filters to create hundreds of traffic routing options

NS1’s DNS filters are like little programs that run inline for every DNS query and are attached directly to RFC-compliant DNS records. Only NS1's filters go beyond simple availability and geographic filters. You can apply availability and geography-based filters alongside incredibly useful filters such as shed load, stickiness, shuffle / weighted shuffle, net fence prefix, ASN, Pulsar RUM-powered real-time user data, and more. The NS1 filter chain engine automatically selects the best response based on the easy-to-configure rules you define. This gives you the power to route users based on which result will deliver the fastest response, highest throughput, or optimize CDN usage. Other DNS providers simply cannot do this because they rely on their own proprietary DNS record types for one-off routing strategies that are inflexible and are extremely difficult to scale. NS1’s filters are easily combined and re-ordered to build simple to complex algorithms tailored to your precise business requirements.
