Many legacy systems or third-party APIs require you to allowlist specific IP addresses to grant access. Using static IPs ensures your connection isn't blocked when Cloudflare’s shared pool rotates.
Organizations often need static IPs to integrate with specific SD-WAN or hardware-based firewall configurations. cloudflare static ips
When you proxy a site through Cloudflare, the DNS records typically resolve to a revolving set of shared IPs. In contrast, a static IP is a specifically assigned, permanent address that does not change without notice. Many legacy systems or third-party APIs require you
Future research should focus on:
Cloudflare’s use of static IPs is a form of "elegant brutalism" in network architecture. It rejects the modern obsession with ephemerality, choosing instead to build a fortress around a fixed coordinate. For the vast majority of web users, this model is invisible and highly effective—it stops massive botnets cold and speeds up global routing. When you proxy a site through Cloudflare, the
Cloudflare's static IPs provide several benefits, including improved security, increased reliability, and enhanced performance. However, they also present some challenges, such as the need to configure firewall rules and routing settings to accommodate Cloudflare's static IPs. By following best practices and using Cloudflare's tools and features, users can get the most out of Cloudflare's static IPs and optimize their network settings for improved performance and security.
