RPKI route origin validation · Japan (networks)
What share of networks in Japan have no RPKI ROA, so their route origins cannot be validated?
43.39% of networks in Japan (95% CI 39.88–46.97%), measured across 749 networks on 2026-10-01.
Measured every Sunday since 2026-08-01 — 15 observations to date. Last measured 2026-10-01.
How this is measured
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.
Built entirely from public bulk feeds — no target is contacted. Aggregate-only. 95% Wilson confidence intervals. Population: networks observed announcing at least one prefix in RIPE RIS, attributed to a country and RIR from the RIR delegated files. Snapshot: rpki-announcing-asns.

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 of this measurement
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.
