Wildcards in IP list

Hello @sergiomarchesini !
There is no plan to add wildcards in the IP list because it could be abused too easily (here, a list enforces paying attention to the settings).
However, there is a filter allowing to overwrite the behavior of the IP whitelist validation:
apply_filters( 'wprus_is_authorized_remote', (bool) $is_authorized_remote, (string) $method, (string) $remote_addr, (mixed) $ip_whitelist );
