 "measurement": "**bulk feeds only — no network is probed.** RIPE RIS gives the ASNs actually announcing routes (the population, so dormant allocations don't inflate the rate); the five RIR delegated-extended files give country and RIR (the segments); the RPKI validated ROA payload gives which ASNs publish ROAs. Population unit: **ASN**; segmented by country and RIR.",
 "why_it_matters": "~37% of announcing networks publish no ROA. Their route origins cannot be validated, so a hijack of their prefixes is cryptographically indistinguishable from a legitimate announcement — traffic can be diverted with nothing to reject it.",
 "limits": "Measures **ROA publication, not per-prefix validation state** — an ASN with a ROA may still announce prefixes its ROAs don't cover. Segments are country/RIR, **not** company size: a different axis, stated as such rather than forced into the SME frame.",
