Carriers adopting DNS for security and network optimization


The domain name system (DNS) was created 30 years ago to make the Internet simpler to use and more controllable. It has evolved to ensure greater network performance, working against malware attacks. Now, DNS is being used by telecom providers to provide security and meet some recent needs such as addressing the bring-your-own-device (BYOD) phenomenon.

“Telecom providers are feeling the pressure from increased data growth,” said David Contreras, VP of corporate marketing at Nominum, during a video interview. “At the same time, they are facing competition from over-the-top (OTT) applications that in some cases are taking away revenue sources. This puts pressure on telecom providers. They need to upgrade their networks, which is very expensive, but they also need to provide new services to remain competitive and relevant.”


Contreras pointed out that different regions in the world have different challenges. In Latin America, the challenge is security: to detect and stop malware attacks. He said that Latin America is a very important market and about 20% of Nominum’s business comes from the region.

During Futurecom 2011, RCR Wireless News interviewed Paul Mockapetris, chairman and chief scientist of Nominum, and Gary Messiana, CEO of Nominum.
