The input is a newline-delimited list of domain names or URLs. The output will be of the form <domain> <ip1> <ip2> .. <ipN>.
echo 'google.com' | ./bulkdns
google.com 74.125.239.34 74.125.239.46 74.125.239.38 74.125.239.33 74.125.239.36 74.125.239.35 74.125.239.40 74.125.239.39 74.125.239.32 74.125.239.37 74.125.239.41
-p will keep the output prefix exactly like the input prefix. By default, the behavior is to prefix the output with only the domain name.
