php loop

[richie]

I need to create a loop that returns all values between the ip range:

0.0.0.0 and 255.255.255.255

I started off like this, but got stuck:

$ipUpper = "255.255.255.255";

$octets = explode(".",$ipUpper);

for($i=$octets[0]; $i==0; $i--) {

...

}

TIA.

<?php
for($i=0;$i<256;$i++) {
    for($j=0;$j<256;$j++) {
        for($k=0;$k<256;$k++) {
            for($l=0;$l<256;$l++) {
                echo $i . '.' .  $k. '.' . $j. '.' . $l . '<br />';
            }
        }
    }
}
?>

However this is 256⁴ strings which is 4,294,967,296 ip addresses.

Beautiful! Thanks a lot.

I realize the size of the output, but I'm working on a script that maps a visitor's ip to his location. A lot of the ip addresses won't have matching locations, hence, I'll the ultimate size would be smaller.

for($i=0; $i<=4294967295; $i++)
{ echo long2ip($i),"<br />";
}
