Goal: Write a BASH Script that traverses the DNS Tree and validates responses from Name Servers at the same level are providing the same response.

DNSStuff.com provides this service for their paid offerings, however it should be fairly straightforward to script.

Once the BASH script has been written, it would be really cool to have a tool visualize the output in a web browser using some kind of Javascript.

Update: I started writing a set of DNS tools in PHP with calls to dig and they are available at http://dns.winvive.com
