Redwood City, Calif. – April 9, 2008 — Nominum, the leading provider of network naming and addressing technologies, today announced its expansion into the large enterprise market with its carrier-proven line of DNS and DHCP software solutions to deliver guaranteed network availability, greater scalability, deployment flexibility and attack resilience.

Nominum is applying its decades of experience and innovation in DNS and DHCP by offering its written-from-scratch software solution to large mission-critical enterprise networks overcoming the issues and challenges that are unsolved by alternative freeware-based appliances. As large enterprises add more IP devices to their network, implement VoIP and mobility, improve security and reliability, they seek to strengthen their DNS and DHCP services requiring minimal disruptions to their architecture, a smooth migration path, and a flexible deployment approach that are all achieved faster and easier with Nominum’s software.

“Unlike the freeware-packaged appliance solutions offered to enterprises today, Nominum’s software solutions help enterprises fully leverage investments in server hardware, eliminate network reconfiguration and stability risks to ensure always-on uptime and help secure the network against attacks and vulnerabilities,” said Tom Tovar, chief executive officer, Nominum. “Over the past year, several enterprises have sought out Nominum as an alternative to appliances and freeware, particularly as they undergo network transformations to support VoIP, Wi-Fi, virtualization, and data center consolidation.”

According to global marketing intelligence firm IDC, most influential large IT departments and large corporations will remain committed to software-based DNS/DHCP products. Because major multinational businesses run complex networks and require the ability to integrate into current network management systems, a robust DNS/DHCP software offering remains the preferred solution.

All large enterprises invest considerable sums in network-certified hardware from proven vendors. With Nominum, a large enterprise has an easy upgrade for its DNS and DHCP infrastructure, preserving and extending the life of existing hardware while achieving unbeatable reliability, better performance and scalability, stronger security, and unmatched operational ease and simplicity.

“Sun's experience in the carrier market and three-year relationship with Nominum confirms the importance high performance and highly scalable DNS and DHCP software makes to IP applications in large networks,” said Juan Carlos Soto, VP of Global Market Development and Engineering, Sun Microsystems. “Solutions built using Sun network computing technologies including the open source Solaris operating system and Sun servers, combined with Nominum’s DNS and DHCP software, provide enterprises the safest investment while achieving the highest quality and reliability in the network.”

The following Nominum enterprise solutions are available immediately under a flexible licensing approach that is tailored to meet the ROI and TCO goals.

• Enterprise DNS package: It includes Nominum’s Authoritative Name Server (ANS) and Caching Name Server (CNS). ANS is a dedicated authoritative name server purpose-built to scale to large number of zones and records. CNS is a dedicated caching-only name server designed for recursively resolve domain names while also protecting the DNS infrastructure against Denial of Service (DoS) attacks and cache poisoning.
• Enterprise DHCP package: It includes Nominum’s Dynamic Configuration Server (DCS), which offers commercial-grade DHCP server with high availability, resiliency and open APIs for flexible DHCP policy management.

Nominum DNS and DHCP packages are supported on any x86 and SPARC-based hardware servers, as well as Red Hat Linux, Solaris and FreeBSD operating systems.
