One of the key features of Cloudflare is its use of static IP addresses, which are used to route traffic to and from Cloudflare's network. These static IPs are assigned to Cloudflare's data centers and are used to identify specific Cloudflare servers.
/24 range), Cloudflare can announce these IPs from its global network, essentially making your existing static IPs part of the Cloudflare infrastructure.

The primary justification for static IPs is Distributed Denial of Service (DDoS) mitigation. In a traditional setup, an attacker who discovers a website’s origin IP can bypass the CDN entirely. However, because Cloudflare’s IPs are static and well-known, the company has inverted the logic. Instead of hiding the IP, Cloudflare has fortified it to an extreme degree. /24 range), Cloudflare can announce these IPs from
Cloudflare is a popular content delivery network (CDN) and security platform that provides a range of services to protect and accelerate websites. One of the key features of Cloudflare is its use of static IP addresses, which can be used to configure firewall rules, routing, and other network settings. In this paper, we will review the concept of Cloudflare static IPs, their benefits and limitations, and provide a detailed analysis of their use cases, configuration, and management.
