+ 1st option

At the http level:

geo $forbidden_client {
    default 0;
    1.0.0.0/8 1;
    12.0.0.0/8 1;
}

server {
    # ...   

    error_page 418 /custom_message.html;

    if ($forbidden_client) {
        return 418;    
    }
}


+ 2nd option


server {
    # ...   

    error_page 403 /custom_message.html;

    deny 1.0.0.0/8;
    deny 12.0.0.0/8;
    allow all;
}
