Whitelist IP Address Feature?

Hi,

I know you answered this question 6 months ago.
However I’d be very happy to see a whitelist added to the plugin.

I tried to do add it myself by looking up within function isLockedDown().

1. My idea was to add a third table say $wpdb->prefix . “lockdowns_whitelist”.
Then do something like :

$white_table_name = $wpdb->prefix . "lockdowns_whitelist";
	$white_subnet = calc_subnet($_SERVER['REMOTE_ADDR']);
	$whitelistedquery = "SELECT user_id FROM $white_table_name " . 
					"WHERE ip = %s";
					
	$whitelistedquery = $wpdb->prepare($whitelistedquery,$white_subnet[0] . "%");
	$whiteListed = $wpdb->get_var($whitelistedquery);

2. Then compare both $stillLocked to $whiteListed.
Something like :

 if ($whiteList) {
    return false;
  } else {
    return  $stillLocked;
 }

However this doesn’t work.
I think I don’t get how function calc_subnet() works.

Would you have any insight for me?

This feature would really help a lot, as I’m regularly not being able to log in and have to use a VPN to circumvent.

Thank you for your feedback.
