Introducing IP Lists

Cloudflare has introduced IP Lists, a new feature that enables users to manage tens of thousands of IP addresses across all zones by grouping them in data structures. This enhances network-based security controls and allows for more complex logic implementation. IP Lists can be used with Firewall Rules engine to take action on incoming requests. The feature offers increased flexibility compared to previous tools like IP Access or Zone Lockdown rules, allowing users to create lists with any prefix length and combine them with other filter criteria. Additionally, IP Lists are stored at the account level, making it easier to reuse across multiple zones. Cloudflare plans to add more capabilities in the future, such as increasing quotas for paid plans, adding additional types of custom Lists, expiring List entries, and creating managed lists.
