NeuStar’s Root DNS service will serve two functions: first, to register domain names under the suffixes “gprs” and “3gppnetwork.org,” which are used to register private domain names that allow operators to retrieve routing information when a subscriber accesses data and multimedia services on a roaming or home network. For example, a U.S. mobile subscriber traveling on business in Singapore will be able to access a video or audio file using their mobile device while roaming on a local GSM network.

Additionally, NeuStar will operate the master DNS root server and provide updates to GRX (GPRS Roaming Exchange) and MMS (Multimedia Messaging Service) providers, allowing mobile operators to access updated DNS routing information. “NeuStar’s Root DNS service supports carrier-grade reliability and availability, ensuring seamless business operations involving DNS, such as domain name registrations, calls, messages and session processing,” said Jeff Ganek chairman and CEO, NeuStar. “Due to IP-based network convergence, NeuStar’s DNS services will play an increasingly vital role in the mobile industry for data and content services such as multimedia messaging services (MMS), push-to-talk over Cellular (PoC), and IP multimedia service (IMS).”
