Due to the GDPR and data protection regulations in the EU, it is not permitted to store the user's personal data without the user's active opt-in consent. This also includes the IP address. If you want to avoid the IP address notice, you can avoid saving the IP address at all.
The easiest way to do this is to add a small bit of PHP code into the WP theme's functions.php.
The following code ensures that WP no longer stores the IP address for comments:
<?php
function wp_no_comments_ip( $comment_author_ip ) { return ''; } add_filter( 'pre_comment_user_ip', 'wp_no_comments_ip' );
?>
