The DNSSEC-Check applications examines the system's configured recursive resolvers for client-side DNSSEC support. It will perform a number of tests and display red, greeen or yellow lights based on its findings. In order for an end-system to perform DNSSEC queries through the resolver, each of these bubbles should ideally be green. Once the data has been collected, it can be submitted to a collection server and a report will be returned showing the current state of the DNS resolvers measured so far.
IMPORTANT: This will launch and require you install the Ministro II service if you do not have it installed yet. Later it will require downloading some additional libraries as well if you don't have them yet. This will only happen once though.
