NeuStar Launches DNS Advantage Service

Advanced recursive service brings new levels of Internet security and performance

STERLING, Va. -- NeuStar, Inc. (NYSE: NSR) today announced its new DNS AdvantageTM offering. Developed by the world’s leading provider of managed Domain Name System (DNS) services, DNS Advantage is an advanced managed recursive DNS service. It is being provided free of charge, and enables connectivity providers, enterprises, and other organizations to offer their end users a safer, faster, and more reliable Internet experience.

Recursive servers are the first step for all Internet activity, as they begin and end the DNS resolution process that directs users to their desired destinations. The primary purpose of a recursive server is to provide an end user with an authoritative IP address that corresponds to the user’s requested domain name. The IP address will either already be in the recursive DNS server’s cache, or the server will query the Internet’s authoritative DNS servers to get the IP address.

While the authoritative DNS infrastructure deservedly receives significant attention, as it supports the address of every domain on the Internet, the majority of DNS query responses are, in fact, generated from the cache of recursive servers. Despite this, the recursive DNS infrastructure of the Internet has received little attention from the technical community, and has generally been left to ISPs to maintain and upgrade on a “best efforts” basis.

“NeuStar has invested significantly over the past eight years in developing the most secure and reliable authoritative DNS infrastructure available,” said Ben Petro, senior vice president of NeuStar Ultra Services. “We are now leveraging our experience and expertise to address the recursive DNS infrastructure, which has become a major impediment to Internet performance as well as one of its major security exposures.”
