DIY BYOIP: a new way to Bring Your Own IP prefixes to Cloudflare

Summary

The article introduces Cloudflare's self-serve Bring Your Own IP (BYOIP) API, which allows customers to onboard their own IP prefixes without manual intervention. This new API automates the traditionally complex process of IP address management, utilizing Resource Public Key Infrastructure (RPKI) for enhanced security and efficiency. By eliminating the need for manual reviews and paperwork, Cloudflare aims to streamline the onboarding process, reduce deployment times, and improve overall security posture. The article also discusses the technical underpinnings of the BYOIP process, including the use of Internet Routing Registries (IRRs) and reverse DNS for ownership verification.
