dns-masscan is a tiny script that automates the process of resolving IP addresses from multiple host names.
The dns-masscan project is sponsored by CGI.
You can download dns-masscan by cloning the Git repository:
git clone https://github.com/p33kab00/dns-masscan.git
dns-masscan works out of the box with any system shell.
Lookup IP addresses from a list of host names:
$ cat hosts.lst
google.com
yahoo.com
cgi.com
$ ./dns-masscan.sh hosts.lst
