Feature: ISP provider domain whitelist filter about wordpress-ip-geo-block HOT 4 CLOSED

You mean that you want to put your domain name into Whitelist of country code instead of putting 2 letters of country code, am I right?

I think it's easy to configure your .htaccess (or something) to restrict IP addresses or domains for wp-login.php.

How do you think?

No, what I mean here is to use provider domain instead of (unknown) provider IP address range.

Afaik, .htaccess has same limitation as IP white/black list. It accepts only IP numbers.

Any country usually have more than one internet provider.
I guess, most of internet provider domains do not cross country borders.
In example, "US" country filter makes huge number of IP accessible to login.
But each ISP provider in US (I guess) uses his own domain to assign reverse lookup for connected (dhcp) clients.

Actually this would be reverse lookup of visitor IP compared with isp provider domain.
Something like

if (preg_match( "/gethostbyaddr(visitor-ip)$/", $provider-domain)).

where visitor IP (123.34.56.78) reverse lookup is "123.34.56.78.adsl.provider.net" and filter is ".adsl.provider.net"

Hi @ddur,

I got your point. Then how about this:

function my_allow_domain( $validate ) {
    $allowed_domain = 'your.domain';
    $visitor_domain = gethostbyaddr( $validate['ip'] );

    if ( preg_match( "/${visitor_domain}$/", $allowed_domain ) ) {
        $validate['result'] = 'passed';
    } elseif ( ! defined( 'DOING_AJAX' ) ) {
        $validate['result'] = 'blocked';
    } // else WP-ZEP block a malicious request

    return $validate;
}
add_filter( 'ip-geo-block-login', 'my_allow_domain' );
add_filter( 'ip-geo-block-admin', 'my_allow_domain' );
