Discovers hostnames that resolve to the target's IP address by querying the online database at http://www.bfk.de/bfk_dnslogger.html.
The script is in the "external" category because it sends target IPs to a third party in order to query their database.
This script was formerly (until April 2012) known as hostmap.nse.
If set, saves the output for each host in a file called "<prefix><target>". The file contains one entry per line.
If set, add the new hostnames to the scanning queue. This the names presumably resolve to the same IP address as the original target, this is only useful for services such as HTTP that can change their behavior based on hostname.
