At one point on was so disappointed with the DNS diagnostic tools that
are around that I started writing my own DNS trace tool, but half way
through I stumbled across http://www.squish.net/dnscheck/v1.html
(recently replaced with an inferior version at http://dns.squish.net/)
which did everything I needed so I never completed the project.

The only problem being that this tool is hosted from a single server
and isn't downloadable to install on your own servers afaik (also
IPv4-only), if anyone knows any similar open source tools I can stick
on my servers that would be extremely helpful and would give me an
excuse to never finish the project!
