# Lists

Cloudflare Lists is a WAF feature that enables administrators to groups identifiers together, such as IPs, hostnames or ASNs, and reference the list by other Cloudflare products such as [Custom rules](https://developers.cloudflare.com/waf/custom-rules/). Cloudflare currently supports the following types of lists:

* [Custom Lists](https://developers.cloudflare.com/waf/tools/lists/custom-lists/): Includes custom IP lists, hostname lists, and ASN lists.
* [Managed Lists](https://developers.cloudflare.com/waf/tools/lists/managed-lists/): Lists managed and updated by Cloudflare, such as Managed IP Lists.

## Objectives
