Introducing IP Lists
Jul 22, 2020Patrick R. Donahue
Summary
Introduced IP Lists as a new data structure for managing IP addresses, ASNs, and countries at the Cloudflare edge. IP Lists allow for arbitrary prefix lengths, are stored at the account level for cross-zone use, and support bulk uploading via CSV or API. They integrate with the Firewall Rules engine, enabling more flexible and complex network-level security policies compared to legacy IP Access and Zone Lockdown rules. Planned enhancements include increased quotas, additional list types, expiring entries, and managed lists.
