DNS Advantage is a proprietary, opt-in, free recursive cloud-delivered DNS service by Neustar launched 11 December 2007 [2] providing two recursive nameserver addresses for public use, mapped to the nearest operational server location by anycast routing.


It provides the following two recursive nameserver addresses for public use:


Current services are limited to DNS resolution and blocking of malicious or questionable websites. Independent testing of the malicious site blocking shows that the block list is limited.[3]

Planned services are:

  • Typographic correction
  • Management dashboard
  • Domain filtering 'site blocker'[4]

As of September 2009, DNS Advantage provides geographically distributed servers in 15 locations on 5 continents.
The cities hosting their servers are:

North America

Four more locations are planned during 2008 to Canada, South America and the Middle East.[5]


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.[6][7][8] While UltraDNS provides DNS services to many household names such as Amazon.com, Gap, MySpace, LinkedIn and Oracle amongst others,[9] it is not clear who utilizes the free DNS Advantage service. The free service is in direct competition to OpenDNS.[10] Like its competitor, DNSAdvantage is based on closed-source software.
