DNS Advantage is a free, closed-source, DNS resolution service. It provides the following two recursive nameserver addresses for public use, mapped to the nearest operational server location by anycast routing:

- 156.154.71.1
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 [1]. [2] While UltraDNS provides DNS services to many household names such as Amazon.com, GAP, MySpace, LinkedIn and Oracle amongst others [3], it is not clear who utilizes the free DNS Advantage service. The free service is in direct competition to OpenDNS.
As of August 2008, DNS Advantage provides geographically distributed servers in 14 locations on 5 continents.
The cities hosting their servers are
* Ashburn VA,
* Chicago IL,
* Dallas TX,
* Miami FL,
* New York NY,
* Palo Alto CA,
* San Jose CA,
* London UK,
* Luxembourg,
* Johannesburg South Africa,
* Beijing China,
* Sydney Australia,
* Hong Kong
* and an undisclosed location in India.
Four more locations are planned during 2008 to Canada, South America, & Middle East.
