Create ACL

You need to create an Access Control List (ACL) if Cloudflare is your secondary DNS provider. The ACL will specify additional NOTIFY IPs that Cloudflare should listen to.

An ACL is configured at the account level, which means that it will apply to every primary and secondary zone in your account.

Dashboard

To create a new ACL using the dashboard:

1. Log in to the Cloudflare dashboard ↗ and select an account.
2. Go to Manage Account > Configurations.
3. Go to DNS Zone Transfers.
4. For ACL, click Create.
5. Enter the following information:
   • ACL name: Provide a descriptive name.
   • IP range: Enter a range of IPv4 or IPv6 addresses (limited to a maximum of /24 for IPv4 and /64 for IPv6).
6. Click Create.

API

To create a new ACL using the API, send a POST request.
