Currently, the DNS community has limited visibility of the capabilities and deployed features of the millions of recursive resolvers in use across the internet. A helpful source of data has been provided by APNIC over the last decade or so by the use of Google Ads but it has been felt that having alternative more accessible methods of collecting this data would be advantageous and provide more flexibility going forward.

The DNS Research Federation have been commissioned by ICANN OCTO to develop an open source testbed suitable for use by organisations with high query traffic, utilising popular open source DNS and Web servers to facilitate the testing of Resolver Capabilities and rational collection of data for analysis. The intention is to provide a good range of DNS feature tests out of the box to allow organisations to perform specific feature testing for themselves as well as to encourage contribution of general data trends to the wider community.

As development of this tool is scheduled for completion in advance of DNS-OARC 42 we would like to take this opportunity to present both the architecture and design of the testing tool as well as to potentially share some initial findings arising from use of the tools in initial testing.
