This is my first ever program and I need some peer review on the code and also have a few questions. I've read the Net::Ping documentation and Learning Perl 4th edition.

use Net::Ping;
@host_array = ("4.4.4.4", "127.0.0.1", "123.333.333.333");

$p = Net::Ping->new("icmp");
foreach $host (@host_array) {
print "$host is dead\n" unless $p->ping($host, 2);
print "$host is alive.\n" if $p->ping($host);
}
$p->close();

- seems like I need to run the program as root or else I get an error: "icmp ping requires root privilege at perl_ping.pl line 10" - is there any way to fix this?

- what is the "2" in print "$host is dead\n" unless $p->ping($host, 2);?

- If I want to have IP addresses like: 1.1.1.0/8 or 203.10.22.19 to 203.10.22.255 is there any shortcut way to put this in the @array?

Thanks for any help.
