About RPKI

Resource Public Key Infrastructure (RPKI) enables network operators to cryptographically attest to the IP prefixes they are authorized to originate.

A Route Origin Authorization (ROA) binds an IP prefix to an AS number, allowing routers to validate BGP announcements and reject hijacks.

Trust Anchor Coverage
