GeoIP IPv4数据库返回错误的国家/地区代码 - 需要进行GeoIP更新？

Question

I am using the following code with the IPv4 database, however I am noticing a number of IP addresses coming with the wrong country code.

Is there a updated binary GeoIP database for IPv4?

Looking at http://maxmind.com/download/geoip/database/ it appears there are only updates for IPv6.

include("geoip.inc");

$gi = geoip_open("/usr/local/share/GeoIP/GeoIP.dat",GEOIP_STANDARD);

echo geoip_country_code_by_addr($gi, "24.24.24.24") . "\t" .
     geoip_country_name_by_addr($gi, "24.24.24.24") . "
";
echo geoip_country_code_by_addr($gi, "80.24.24.24") . "\t" .
     geoip_country_name_by_addr($gi, "80.24.24.24") . "
";

Answer 1

It appears that GeoIP do update the IPv4 database and they are made available here. They state that they update it on the first Tuesday of every month and it is available for free.

I was probably using an old version of the binary database, and after updating it the IPs were returning the correct country code.
