IP Filters are rules you can apply to records across multiple domains and when a user meets the requirement(s) of the filter, they will be answered with that record. Otherwise, they will be answered with the World/Default record. You MUST have GeoIP services enabled for your domain in order to use IP Filters.
Important: Before you apply an IP Filter to a record, you must create a record of the same type that will be used to answer queries that don’t match your filter. Apply the World/Default IP Filter to that record.
Please Note: IP Filter rules will supersede any Geo Proximity rules that are configured
1. Navigate to Advanced > IP Filter.
2. There will already be one filter available called “World”. This is the default IP filter. To create a new filter, click on the button.
3. You will then be prompted to create your IP Filter. Please follow the directions below:
A) Name: Enter an easily identifiable name for your filter. You will need this later when you use it with a domain. B) Filter by: You can choose from any of the four options to create your filter: Location, ASN, /24 IPv4 EDNS client subnet or /120 IPv6 EDNS client subnet. C) Add: You can select more than one option, just make sure you click the button after each choice. Each filter you add will appear in the shaded box on the right. D) Save: Once you have added all of your filters, click the Save button.
If you would like to remove a filter, just click the button next to one you want to remove. After you create an IP filter, you can feel free to apply the IP filter to a record within a domain.
