It’s not unusual to store IP addresses in a database using a network long. First, it’s space efficient. Second, an integer format allows you to easily (and inexpensively) query for IPs which fall into a given subnet or address range. Doing this with DDN (dotted decimal notation) formatted columns is far more difficult.
A DllCall to wsock32.dll’s inet_ntoa() function will simplify your code (even eliminate the intermediate dec2hex conversion). This DLL has additional similar functions for address manipulation.

Or you can use the following php function
function address2number($ip){
$retVal = false;
list($a,$b,$c,$d) = explode('.', $ip);
if(is_int($a) && is_int($b) && is_int($c) && is_int($d)){
$retVal = ($a
I use this code on my website: Ip global positioning . I have also google maps API to show the exact location.
