Hi MOnks, Please suggest how can I check opened port for range of IPs. Below is my code 
#!/usr/bin/perl
# TCP Port scanner
print q{
=================================================
    SIMPLE TCP PORT SCANNER

    Coded by: CKJ
=================================================
    };
use IO::Socket;
$source_dir= "C:/ips.txt";
open(FH,"$source_dir") or die $!;
while(my $line= <FH> ){
    while($line=~/(\d+.\d+.\d+.\d+)-(\d+.\d+.\d+.\d+)/g){
        print "IPs are: $1 to $2\n";
        $min_ip = $1;
        $max_ip = $2;
        for (; $min_ip<=$max_ip; $min_ip++) {
           my %ports = (80,8080,81,8181);
           my ( $daddr );
           {
           $daddr = inet_aton($min_ip) || die("Failed to locate target
+ host: $target");
           print " ===================================================
+=============\n";
           print " Scanning $min_ip on ports $port-$maxport\n";
           print " This might take a while depending on how many ports
+ you have\n";
           print " ===================================================
+=============\n";
           foreach $port(%ports) {
               print "\n == Scanning port $port ==";
               if( IO::Socket::INET->new(PeerAddr=>"$min_ip:$port",Pro
+to=>'tcp',Timeout=>1))
               {
                   print "\n==== Port $port is open ====\n" ;
               }
               else{
                   print "\nPort $port is NOT open\n";
               }
           }
           }
        print "\n\n\nFinished Scanning $min_ip up to port $maxport\n\n
+";
       }
    }
}
print "\n Thanks for using my port scanner\n";
exit (0);
close (FH);

The ips are right now taken from a text file which format is something like this: ips.txt:
