By now, I think everyone has heard about the cache poisoning vulnerability in many DNS servers. Many are using Dan Kaminsky's online testing tool at doxpara.com to test their own servers, but Dan's server leaves the results exposed to the public. For those that want to test their DNS servers and not have the results [...]
