All of these tests are possible using command line tools, but some of them would require multiple invocations of the tools, as well as verification against a matrix of known-good configuration parameters. For example, the DNS report is pretty comprehensive.
What's surprising to me is that these tools are web based. Although, there is some value in having a third party verify your assumptions. It's not uncommon for me to alter my hosts file while I wait on DNS to propagate. That can screw up my resolver when running diagnostics locally.

Watchmouse seems to have been bought out recently too, hope they don't go pay.
Oh apparently they have been on here before, just not the main page http://www.hnsearch.com/search#request/all&q=viewdns.inf...
