gethostbyname command line

Pasteable script below. I can't believe this doesn't exist. No command line tool to get a host name using the resolver on linux?

use Socket;

$host = shift @ARGV;
die("usage: gethostbyname hostname\n") unless(defined($host));

$packed_ip = gethostbyname($host);

if (defined $packed_ip) {
$ip_address = inet_ntoa($packed_ip);
print "$ip_address\n";
exit 0
} else {
warn "$host not found\n";
exit 1
