IBM NS1 Connect
Improve reliability and resilience
Experience the power of authoritative DNS service to keep users connected and revenue flowing with a global anycast network featuring a 100% DNS uptime service level agreement (SLA).
DNS servers can be subject to attacks that deny access to domains, overwhelm servers with traffic or take over DNS infrastructure. NS1 provides built-in resilience against distributed denial of service or DDoS attacks, including volumetric DDoS surges for improved DNS security. For added resilience, an optional single-tenant redundant domain name system (DNS) layer is also available.
Optimize DNS infrastructure
Your anycast DNS solution needs to have advanced, customisable traffic steering, Real User Monitoring (RUM), global server load balancing (GSLB DNS) and multi CDN capabilities to help ensure that you can deliver applications, services and content with the performance your users expect.
Streamline DNS management
Automate the full range of cloud DNS configuration tasks through the IBM® NS1 Connect® application programming interface (API). Manage both primary DNS and secondary DNS with ease, using preconfigured integrations for application monitoring, observability and infrastructure as code (IaC) to reduce manual effort.
