IP address not correct on some websites using IP Geo Block.

Hi ac1643,

As I told about this issue in email, I think your site might be within the LAN or behind the proxy server. Because the IP addresses from 10.0.0.0 to 10.255.255.255 are assigned as private IP address. Those should not be in the public.

--------+-------------------- Internet
        | 90.200.*.*
      server
        | 10.170.*.*
    ----+--------------+----- Local Area Network
        |              |
    your computer    others

Your server’s IP address looks 90.200.*.* from the internet but it looks 10.170.*.* from the LAN.

IGB uses PHP environment value $_SERVER['REMOTE_ADDR'] that your computer assigns. And it’s value might be 10.170.0.4. Definitely, IGB does not cause this issue, but it’s inevitable in your environment.

To make the situation better than now,

1. Uncheck all the “Geolocation API settings” but “Maxmind” and “IP2Location“.
2. Put “ZZ” into “Whitelist of country code“.

Or you can put the following snippet into your functions.php:

function my_replace_ip( $ip ) {
    if ( false !== strpos( $_SERVER['REMOTE_ADDR'], '10.170.0' ) )
        return '90.200.xxx.yyy'; // your server's IP
    else
        return $_SERVER['REMOTE_ADDR'];
}
add_filter( 'ip-geo-block-ip-addr', 'my_replace_ip' );

Good luck!

Thanks for this, I will do as you say and investigate the issue a bit further.
