NS1 (now IBM NS1 Connect) is a managed authoritative DNS, traffic management, and DDI platform. Its data-driven DNS steers traffic with real-time telemetry (Pulsar RUM), health-check monitoring, filter-chain traffic-steering policies, GeoDNS, and dedicated DNS. Everything is programmable through the NS1 REST API at api.nsone.net/v1, authenticated with an X-NSONE-Key API key, and supported by first-party SDKs (Python, Go, JavaScript, PHP), an Ansible module set, a Terraform provider, and a command-line interface. NS1 was acquired by IBM in 2022 and is delivered as IBM NS1 Connect; the api.nsone.net API host and v1 contract remain unchanged.
