Hide Commenter IP Addresses From Non-Administrators

Hides commenters' IP addresses in the Comments screens for editors, moderators and authors, so only administrators can see this personal data.

Code

add_filter( 'get_comment_author_IP', function ( $ip ) {
    return current_user_can( 'manage_options' ) ? $ip : '';
}, 20 );

Administrators (users who can manage options) still see the full IP address.
