IBM NS1 Connect — Managed DNS Platform

Enterprise-grade managed DNS with traffic steering, real-time analytics, and global anycast network.

What Is IBM NS1 Connect

IBM NS1 Connect, formerly known simply as NS1, is a premium managed DNS platform acquired by IBM in 2024. The service provides authoritative DNS hosting with advanced traffic steering capabilities, real-time analytics, and enterprise-grade reliability through a global anycast network.

NS1 was founded in 2013 and quickly became known for its innovative traffic management features. Its Filter Chain technology allows DNS responses to be dynamically modified based on real-time data about server health, geographic location, network latency, and user-defined rules. This makes NS1 a popular choice for organizations that need sophisticated traffic routing, including CDNs, streaming platforms, and e-commerce companies.

Under IBM, NS1 has been rebranded as IBM NS1 Connect and integrated into the IBM Cloud ecosystem. The platform continues to operate independently while gaining access to IBM's global infrastructure and enterprise customer base.

Key Features

IBM NS1 Connect offers managed DNS hosting with a 100% uptime SLA, global anycast network spanning 25+ points of presence, real-time traffic analytics, API-first architecture for automation, and advanced traffic steering through its Filter Chain system. The platform supports all standard DNS record types and offers DNSSEC signing, secondary DNS, and zone transfers.

The platform's API-first design is a key differentiator. All DNS management operations can be performed through RESTful APIs, making NS1 suitable for organizations that manage infrastructure through code (infrastructure as code). Terraform, Kubernetes, and other automation tools have first-class support for NS1's API.

Traffic Steering Capabilities

NS1's Filter Chain system is the platform's most distinctive feature. It allows DNS responses to be dynamically modified based on multiple inputs evaluated in sequence. Filters can route traffic based on geographic region, ASN, response time measurements, server load, and custom metadata. This enables sophisticated traffic management strategies like active-passive failover, latency-based routing, and weighted distribution.

Pricing

IBM NS1 Connect is a premium managed DNS service with pricing based on the number of DNS queries and zones managed. Basic plans start at approximately $50 per month for smaller deployments. Enterprise pricing with custom SLAs and dedicated support is available for large organizations. NS1 does not offer a free tier.

NS1 vs Other Managed DNS Providers

Compared to AWS Route 53, Azure DNS, and Google Cloud DNS, NS1 offers more sophisticated traffic steering but at a higher price point for basic DNS hosting. Route 53 integrates deeper with the AWS ecosystem. Azure DNS is tightly coupled with Microsoft's cloud. NS1's advantage is its vendor-neutral approach and advanced filtering capabilities that work across any cloud or on-premises infrastructure.
