It never stops, it just keeps growing and growing. Getting better and better. I am currently adding CIDR support into the system. Just think of the security this can provide a webmaster.
Add a "Blocked Range" and the system converts the range into a CIDR(s) that can be written to your .htaccess file.
Edit a "Blocked Range" and the system will remove the old CIDR(s) and add the new CIDR(s) to your .htaccess file.
Delete a "Blocked Range" and the system removes the CIDR(s) from your .htaccess file.
Self Expiring "Blocked Ranges" using the same system to release a server level block of a range when it expires out of the database.
