About Us

Neustar (NYSE: NSR) is a provider of clearinghouse and directory services to the global communications and Internet industry.

Founded to meet the new technical and operational challenges of the communications industry when the U.S. government mandated local number portability in 1996, Neustar has evolved to create customer-responsive technologies that deliver a broad range of essential clearinghouse capabilities for service providers. Our clearinghouse enables delivery of traditional services more efficiently and deployment of new services more rapidly than ever before.

Neustar's UltraDNS® service provides solutions to organizations that rely on DNS for their critical business processes, applications, and services, delivering superior security, reliability and performance. With the growth in e-commerce and the emergence of advanced DNS-based communication services, organizations can no longer rely on traditional approaches to DNS.

DNS Advantage was built on and is delivered by the UltraDNS Directory Services Platform, one of the world’s largest proprietary non-BIND DNS networks. Providing integral Authoritative DNS services at the root, for top-level domain (TLD) registries, and for second-level domain (SLD) registrants, Neustar has thousands of enterprise, service provider, and core DNS infrastructure customers. The UltraDNS Directory Services Platform is responsible for powering the resolution of over 20 million domains around the world, and is actively involved at every level of the DNS hierarchy.
