You may want to try.

#!/usr/bin/perl -w

use strict;
use Net::Ping;    
$| = 1;
my @hosts = <DATA>;
my @proto = ("tcp", "udp", "icmp", "stream", "syn");
foreach my $pro ( @proto ) {
    print "\nProtocol $pro \n";
    my $p = Net::Ping->new($pro);
    foreach my $host( @hosts ) {
        chomp($host);
 # Specify source interface of pings
        print "$host is ";        
        print "NOT " unless $p->ping($host, 2);        
        print "reachable.\n"; 
    }  
    $p->close();  
}
exit;
