#### Configuring Domain Name Black List

The Domain Name Black List plug-in works as follows:

- At first, the plug-in takes a customer IP address (i.e., the IP address that a customer comes from to the store is detected automatically and shown in a credit card details or an order details) and searches for a domain name for this IP address.
- If a domain name search fails, the plug-in produces the Error response. You can set the plug-in behaviour in case of errors in the plug-in General Configuration.
- If a domain name is found, the plug-in looks in the domains black list (that can be formulated manually under the plug-in) whether a domain was found is in the black list or not.
- If a domain appears to be in the black list, the plug-in returns alert.

To add a new pattern to the domains black list:

1. Click the Add Domain Name button on the plug-in screen.
2. Enter a domain name (top level domains like .com or .net, etc. are not allowed, you can enter only domain names like blackdomain.com) into the relevant field.
3. Click the Save button.

Repeat the steps described above to add more patterns to the black list.

To remove a domain name from the black list:

1. On the plug-in screen that displays the black list of domain names, check the box next to a domain you want to remove from the black list.
2. Click the Delete button.
