Pass on the Customer IP Information to Authorize.net
Recently one person tried to order our product by using more than 20 different credit cards. We use Authorize.net as the payment gateway. It has a powerful feature called Fraud Detection Suite which allows you to block the transactions based on IP address. But currently 1shoppingcart can't pass on the IP address to Authorize.net. So we can't use that feature to fight against that type of internet scams.

Thanks for the heads up as we are going over to authorize.net shortly! Not a good idea to have a hole in our security as well as our integration
