Reverse IP Logfile Analysis API

Question

I have a list of IP addresses, about 1300, that I need to look up to find out company information or whatever is available from an online tool. I don't mind if I have to pay for it. but I don't want to have to put each one in manually.

Is there something that I can use that would give me this detail that I could either copy or paste or write a quick script for.

Thanks in advance.

This would work on Linux or MacOS. If you're on windows, I"m not sure.

<?php
$ip_file=file('/path/to/file');

if($ip_file===false){ echo "file is unreadable\n"; exit; }
if(empty($ip_file)){ echo "file has no contents\n"; exit; }

foreach($ip_file as $line)
  {
   $ip=trim($line);
  if(strlen($ip)>0){
    echo "IP: $ip : ";
    passthru('host '.escapeshellarg(trim($ip)));
    }
  }
