![[How2] Ip to Country Function Using (Blocking IP Blocks)(With C++ Codes.)](https://www.elitepvpers.com/forum/iconimages/metin2-pserver-guides-strategies/how2-ip-country-function-using-blocking-ip-blocks-c-codes_ltr.gif){kind=small}
OK, Now lets see.
--------------------------------------
First run this query in account database.
PHP Code:
DROP TABLE IF EXISTS `iptocountry`;
CREATE TABLE `iptocountry` (
`IP_FROM` varchar(30) NOT NULL default '',
`IP_TO` varchar(30) NOT NULL,
`COUNTRY_NAME` varchar(30) NOT NULL,
PRIMARY KEY (`IP_FROM`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
OK now lets add some ip's.
IP_FROM: Beginning of the ip block.
IP_TO: Ending of the ip block.
COUNTRY_NAME: You need add some name... Country name etc.
Here is the example image by me:
### This function tested by me and %100 working. ###
Here is the C++ code (All of this function.)
PHP Code:
int __cdecl add_blocked_country_ip(int a1)
{
int v1; // eax@1
int v2; // edx@1
char *v3; // ecx@1
char v4; // zf@1
int v6; // [sp+20h] [bp-8h]@1
v1 = operator new(8);
v6 = v1;
v2 = v1;
v3 = *(char **)&s_blocked_ip[4];
v4 = *(_DWORD *)&s_blocked_ip[4] == *(_DWORD *)&s_blocked_ip[8];
*(_DWORD *)v1 = *(_DWORD *)a1;
*(_DWORD *)(v1 + 4) = *(_DWORD *)(a1 + 4);
if ( v4 )
{

else
