With most configurations, your changes will only apply to the record or domain you are modifying. However, IP Filters can be applied to multiple domains. That means any changes you make to an existing and applied IP Filter will propagate to all the domains it is applied to.
1. In the sidebar menu click on Advanced and then select IP Filter from the drop-down menu.
3. On this screen you can add or remove existing filters. To add a record, select the location or enter the information in the appropriate field, then click the button next to your desired Filter Type. Added records will appear in the shaded grey box on the right side.
4. When you are done, click the Save button. Your changes will be automatically propagated to all applicable domains.
