DNS service provides stability and performance for CIRA and for the holders of .ca domains.

NeuStar, Inc., a provider of clearinghouse and directory services to the global communications and Internet industry, today announced that the Canadian Internet Registration Authority, a not-for-profit Canadian corporation that is responsible for operating the .ca country code top-level domain, has chosen NeuStar's UltraDNS Managed DNS Service to bolster the scalability and reliability of Canada's DNS infrastructure.

The company states that CIRA has leveraged NeuStar's UltraDNS Managed DNS Service to expand its global network footprint in a cost- and resource-effective manner. It says that as the number of .ca domains continues to grow, international DNS network expansion is critical in providing a reliable, high-performance TLD. Rather than expanding its existing DNS network, CIRA is utilizing the UltraDNS platform to increase on-demand capacity to handle large volumes of traffic and also to gain software code diversity within its network environment. Achieving code diversity provides enhanced security, and is becoming standard operating procedure for the TLD community, it adds.

The company further explains that with the UltraDNS Managed DNS Service, CIRA also will benefit from the DNS Shield, an extension of the UltraDNS infrastructure which involves the deployment of authoritative DNS servers within the core networks of leading ISPs, creating a hardened and secure DNS infrastructure that provides protection against Distributed Denial of Service and pharming attacks. It avers that this solution enables secured DNS resolution for end users of partner ISPs for more than 30 TLDs, including .ca, supported on the UltraDNS platform.

"We are very proud to count CIRA as a NeuStar partner," said Rodney Joffe, senior vice president and senior technologist at NeuStar. ".ca is a critical TLD for a significant number of users, and we are pleased to provide advanced DNS services in supporting a key piece of the Internet infrastructure. We look forward to a long and productive relationship."

"Stability and performance are essential for CIRA and for the holders of .ca domains," said Norm Ritchie, chief information officer at CIRA. "CIRA selected NeuStar to complement our .ca DNS infrastructure because they are a recognized leader and innovator, and they have a proven track record of supporting the TLD community with robust DNS solutions."
