IP spoofing / [reserved IPs] simply disallow

The IP address spoofing (in English: IP spoofing or IP address spoofing) is a technique used in computer science that involves sending IP packets using a source IP address that has not been assigned to the computer that issues. The goal may be to hide one's identity during an attack on a server, or somehow usurp the identity of another network equipment to receive services to which they have access.

In the world of international eCommerce, this practice is common, but we can discover that there is a list of reserved IPs that are diverted to take advantage of this technique to prevent spoofing the maximum we can block them directly in the .htaccess file from our server.

To avoid losing data each time you refresh your PrestaShop store .htaccess file, I recommend that you put the .htaccess file at the root of your hosting, as it will be taken into account by all the subdirectories on your server.

Here is the list of data to be inserted in the .htaccess file. The lines highlighted in yellow are optional because they may prevent some customers to visit your store, but they are very beaches IPs used by spammers.
