History
DNS Advantage was launched on December 11, 2007 as a free DNS service. It is built on top of the infrastructure already provided by the commercial, fee based UltraDNS service. Both the free and fee based services are operated by NeuStar. While UltraDNS provides DNS services to many household names such as Amazon.com, Gap, MySpace, LinkedIn and Oracle amongst others, it is not clear who utilizes the free DNS Advantage service. The free service is in direct competition to OpenDNS. Like its competitor, DNSAdvantage is based on closed-source software.
