DNS+ provides visibility into worldwide DNS data, from thousands of vantage points in the form of open resolvers present on the Internet. DNS+ is an optional module that is built to provide DNS visibility over and above the agent-based insight provided by the ThousandEyes platform, and as such, not all organizations will have access to the DNS+ test suite.
The DNS+ Availability view leverages the ThousandEyes DNS+ layout, documented here: https://support.thousandeyes.com/ViewArticle?articleIdParam=kA0E0000000CmmgKAC. This article highlights specifics shown in the DNS+ Availability view.
The example below shows a view of a DNS+ Availability test against the faluninfo.net domain's A record.
The DNS+ Availability view shows two different data views, depending on whether or not a country is selected.

Any view of a network, or Autonomous System (AS) is based on a list of registered Autonomous Systems, or telecommunications provider present in that country. Autonomous System (AS) details can be seen by hovering over the AS link, shown in the network name column of the network tab. An example of this AS information can be found below, showing Telecom Argentina S.A., AS 7303.
