nsho is a free and simple to use script which performs a very basic BIND security audit by way of dig which other tools — such as those located at the now highly commercialized dnsreport.com — do not.
Namely, testing for the display of potentially exploitable version information and willingness to participate in anonymous zone transfer requests.
Just pass nsho your domain name and enjoy the lack of ads as you take a look at all the juicy information your nameservers are actively allowing everyone to see.
