The software can block certain IP addresses from accessing the site.
Note: Be very careful with this feature! Customers' IP addresses will sometimes be for more than just them (office networks, proxies, etc) and you can end up banning more people than you intended. It is also possible to ban yourself if you ban a customer you created in testing.
To block IP addresses:
1. Verify that the ‘IPAddress.RefuseRestrictedIPsFromSite’ AppConfig is set to true.
2. Then go to Orders -> View/Manage Orders.
3. Notice that a ‘Block IP’ button is displayed on each customer’s order.
4. Just click on the Block IP button if you want to block the customer’s IP address.
