Hi All, I am a Perl beginner and I have a whois script that takes IPs from a file and is supposed to grab the ARIN whois information, however I am getting an error:

"Modification of non-creatable array value attempted, subscript -1 at /usr/lib/perl5/site_perl/5.8.8/Net/Whois/ARIN.pm line 391."

Can anyone let me know what I'm doing wrong? Thank you.


#!/usr/bin/perl

use Net::Whois::ARIN;

my $file="file_containing_IPs.txt";

open(LIST,$file) or die "Unable to open file $file:$!\n";

  my $w = Net::Whois::ARIN->new(
              host    => 'whois.arin.net',
              port    => 43,
              timeout => 30,
          );

while(<LIST>) {
  foreach ($_) {
   chomp;
       my @output = $w->network($_);
       foreach my $net(@output) {
       printf(
          "CIDR: %s\tNetName: %s\tNetHandle: %s\n",
          $net->CIDR,
          $net->NetName,
          $net->NetHandle,
       );
      }
  }
}

close(LIST);
