Sorting IP addresses

Allright thanks dereine. I've been reading up abit on how to do such a thing and it looks like I need to create a module, name it "views_sort_ip" for example, create a .module file and a views_sort_ip_handler_field_something.inc. Then copy some code here and there. Only thing I can't seem to find is where or when I can see if what I'm doing is working yet but I'll try and see what happens.

I've never done anything remotely similar in Drupal yet so if you have some pointers or an example that'd be greatly appreciated.

Thanks!

Allright, I've come this far:

file: views_sort_ip.module

function views_sort_ip_views_api() {
  return array(
    'api' => 2,
    'path' => drupal_get_path('module', 'views_sort_ip'),
  );
}

file: views_sort_ip.module

<?php
function views_sort_ip_views_data()
{
  $data['views_sort_ip']['table']['group'] = t('views_sort_ip');
  $data['views_sort_ip']['table']['join'] = array(
    '#global' => array(),
  );

  $data['views_sort_ip']['ip'] = array(
    'title' => t('Sorteren op ip adres'),
    'help' => t('IP adressen sorteren'),
    'sort' => array(
      'handler' => 'views_handler_sort_ip',
      ),
  );
  return $data;
}

function views_sort_ip_views_handlers()
{
  return array(
    'info' => array(
      'path' => drupal_get_path('module', 'views'),
    ),
    'handlers' => array(
    'views_handler_sort_ip' => array(
      'parent' => 'views_handler_filter_numeric',
       ),
    ),
  );
}

file: views_handler_sort_ip.inc

<?php

class views_handler_sort_ip extends views_handler sort {
  function query ()
    $this->ensure_my_table();
    $this->query->add_orderby($this->table_alias, $this->field . $i, $this->options['order']);

Now I don't know how to insert the INET_ATON option into the query. I've seen a few examples but all seemed too complicated for what I need and didn't give me an impression on how to get there.
The ip address is in the default node title field so in mysql it would be: "order by INET_ATON(title);" Besides this, I don't know what will happen when I activate the module. Will I get a new option next to sorting ascending or descending or will the field automatically be sorted this way?

Hope you can help.

Kind regards, Nda
