Internet IP Address 2011 Report

By David on January 19, 2011

IP addresses are allocated on an annual basis by the Internet Assigned Numbers Authority (IANA) and its regional registries to various organizations worldwide with the majority of the IP addresses being allocated to the developed countries like the United States, Japan and the United Kingdom. In the last few years though, emerging economies like China have been allocated an increasingly bigger percentage of the IP addresses. This trend which is also evident in the likes of India, Vietnam and Mexico indicates an ever growing appetite for internet consumption amongst their populations.

In this first section of the study, we breakdown the average percentages of IP address allocations in 240 countries using the IP2Location historical data. The average percentage is the arithmetic mean of 12-month values collected on the first day of the month from the IP2Location monthly database.

From the data analysis (see Table 1 &Chart 1), it is clear that the overall IP address allocations for Asian countries are on the rise whereas European countries have seen a drop in their allocations. Leading the Asian countries is China which has overtaken the United Kingdom for the 2nd highest number of allocations. South Korea, a country famous for online gaming, managed to secure 6th place and has relegated France to the 7th position.

The Top 10 countries in the list still managed to secure 77.73% of the total allocated IP addresses in 2010. That is a decrease from the 2009 total of 79.1%. With the economic upheavals in both the United States and Europe, it is hardly a surprise that the numbers have decreased. On the other hand, it will open up more allocations to emerging countries in Asia and South America.

In this second section of the study, we plot the month-to-month percentage of IP address allocations by country using the IP2Location historical data in 2010.

From the chart analysis (see Chart 2), we can see that the allocation rate is slowing down compared to 11% in 2009. The total IP addresses allocated for 2010 is 2,685,024,462. Compared to the total for 2009 which is 2,505,141,392, we are seeing a 7.2% increase in the total number of allocations.

Considering that the total IP addresses in the IPv4 space is 4,294,967,296, that leaves us with only approximately 37% of IP addresses to be allocated in Class A, B and C.

phpBB Forum user registration integration

By David on October 24, 2009

Just working out on the phpBB3.0 on the user registration integration with the main web site. Because of I plan to write the main web site using the coldfusion + MS SQL, so the only way as I may thinking of to do the integration is write a web service a like page for my coldfusion application to call.

After read through some forum, blog, web site and finally find out the way for the integration and here to share my simple PHPBB 3.0 user registration integration code.

  < ?PHP
  define('IN_PHPBB', true);
  /* set scope for variables required later */
  global $phpbb_root_path;
  global $phpEx;
  global $db;
  global $config;
  global $user;
  global $auth;
  global $cache;
  global $template;

  # your php extension
  $phpEx = substr(strrchr(__FILE__, '.'), 1);
  $phpbb_root_path = "../";

/* includes all the libraries etc. required */
  require($phpbb_root_path ."common.php");
  require($phpbb_root_path ."includes/functions_user.php");
  $use-->session_begin();
  $auth->acl($user->data);

// username of the user being added
$username = 'david';

// the user’s password, which is hashed before inserting into the data base
$password = 'password';

// an email address for the user
$email_address = 'admin@david-cheong.com';

// since group IDs may change, you may want to use a query to make sure you are grabbing the
// right default group...
$group_name = ($coppa) ? 'REGISTERED_COPPA' : 'REGISTERED';
$sql = 'SELECT group_id
        FROM ' . GROUPS_TABLE . "
        WHERE group_name = '" . $db->sql_escape($group_name) . "'
            AND group_type = " . GROUP_SPECIAL;

$result = $db->sql_query($sql);

$row = $db->sql_fetchrow($result);

$group_id = $row['group_id'];

// timezone of the user... Based on GMT in the format of '-6', '-4', 3, 9 etc...
$timezone = '8';

$language = 'zh_cmn_hans';

// here if the user is inactive and needs to activate thier account through an activation link
// sent in an email we need to set the activation key for the user... (the goal is to get it about
// 10 chars of randomization) you can use any randomization method you want, for this example,
// I’ll use the following...
$user_actkey = md5(rand(0, 100) . time());
$user_actkey = substr($user_actkey, 0, rand(8, 12));

// IP address of the user stored in the Data base.
$user_ip = $user->ip;

// registration time of the user, timestamp format.
$registration_time = time();

// time since the user is inactive. timestamp.
$user_inactive_time = time();

$user_row = array(
    'username'              => $username,
    'user_password'         => phpbb_hash($password),
    'user_email'            => $email_address,
    'group_id'              => (int) $group_id,
    'user_timezone'         => (float) $timezone,
    'user_dst'              => $is_dst,
    'user_lang'             => $language,
    'user_type'             => '0',
    'user_actkey'           => $user_actkey,
    'user_ip'               => $user_ip,
    'user_regdate'          => $registration_time,
	'user_dateformat'   	=> 'D M d, Y g:i a'
);

$user_id = user_add($user_row);

echo 'userid' . $user_id;

?>
