@felipe... you're wrong here - this works just fine without having to
cast to float:
[EMAIL PROTECTED]:~$ php-5.2.5RC2
<?php
$ip = "213.10.212.144";
$ipaddr = sprintf("%u",ip2long($ip));
$address = sprintf("IP ADDR = %u", $ipaddr);
echo $address;
?>
IP ADDR = 3574256784d

Ops, ignore the part "ip2long() returns a string."

ip2long() returns a string. Converting this value to float for obtain
large precision, you will have the expected result.
$ip = "213.10.212.144";
$ipaddr = sprintf("%u", ip2long($ip));
$address = sprintf("IP ADDR = %u", (float) $ipaddr);
var_dump(PHP_INT_MAX, ip2long($ip), $ipaddr, $address);
