Cloudflare announces a self-serve Bring-Your-Own-IP (BYOIP) API that automates and secures IP prefix onboarding using RPKI (ROAs) plus IRR or reverse DNS token validation, replacing manual LOA workflows and initially supporting prefixes originated from AS13335. The update adds safeguards like required default service bindings to prevent blackholing, supports multiple services per prefix, and auto-generates documentation to aid global route acceptance, with developer docs available now and dashboard/offboarding features planned—advancing IP address management and routing security.
