GNS is an option for enterprises looking to fully outsource their DNS operations. It provides both primary and secondary service for enterprises seeking a fully outsourced DNS solution. Every GNS level of service comes with a guarantee of near-perfect uptime.
Nominum President and CEO Will Thomas described the service as one that provides "a high degree of reliability and performance to organizations of all sizes who recognize the mission-critical role DNS plays in their business." He further notes that GNS, "goes well beyond the minimal 'best practice' of placing secondary servers on a different network and is much more cost effective."
GNS is based on a infrastructure with multiple sites, servers, and networks. It is designed to deliver the most reliable, fault-tolerant, user friendly DNS possible. Core GNS sites are located at Internet exchange points and thus are optimally positioned for network speed and reliability. Each GNS core location houses multiple servers on different hardware and operating system platforms for maximum security. All sites are redundant in themselves and to each other; so if an entire GNS site fails, other sites around the world continue to serve customers' domain data.
The underlying domain server is optimized for speed of response. The server software is unique in its compliance with Internet Engineering Task Force (IETF) standards, including IPv6 and DNSSEC.
GNS comes with a 99.99 percent uptime guarantee, as well as around-the-clock telephone and e-mail support.
Nominum offers Internet naming and address management solutions that provide the DNS management necessary for virtually all internetworking software. The company is also involved with the writing and implementation of BIND and DHCP, both of which are freely available as open source.
