REDWOOD CITY, California, July 23 /PRNewswire/ --

- Fastest Growing Broadband Provider in Spain Fortifies DNS, Prepares for

Nominum, the leading provider of network naming and addressing
technologies, announced today that ONO, a broadband provider in Spain, has
selected Nominum's carrier-grade DNS as the foundation for its broadband
Internet access service.

With more than 1.2 million subscribers and a network that spans the
country, ONO recognized that the subscriber Internet experience is dependent
on DNS performance and made the decision to upgrade their DNS. Nominum was
the only vendor that offered the performance, resilience, protection against
security threats, and availability that would ensure the secure and quality
Internet user experience ONO has become known for.

With the upgrade, more than 90% of the DNS traffic is handled by three
Nominum DNS servers. The previously deployed open source based solution
required a larger server hardware footprint, and accommodating future DNS and
Internet traffic growth was going to require the addition of even more
servers on a regular basis.

"The broadband market is extremely competitive and ONO has differentiated
by offering the best Internet access services available today. To ensure that
we continue to grow and lead the market we made a decision to upgrade our DNS
infrastructure," said Carlos Moreno, CIO of ONO. "With Nominum software, our
network is faster and simpler; more importantly, we are positioned to take
advantage of DNS based service offerings from Nominum in the future that
further improve our users' Internet experience."

"Nominum's carrier grade DNS allows providers to thrive as more
subscribers use Web 2.0 applications on their networks," said Tom Tovar, CEO
of Nominum. "We are in a unique position to help carriers and service
providers around the world fortify their networks and build value added
DNS-based subscriber services that improve the user experience and
fortify the bottom line."
