Just for the sake of discussion. Have you found a need to use this tool as opposed to using the built-in DNS resolution features built into nmap when conducting a scan?
I haven't had a chance to play with it (yet) but it seems slightly redundant, but extremely useful if it can perform the enumeration without getting the attention of an IDS or IPS.
Regardless, thanks for the post, will definetly play with it soon to see what it can do
