Announced routes

Every prefix a peer of the route collectors sees with origin AS208636, things to look at first. Visibility = full-table peers that see it, of 673 (IPv4) and 636 (IPv6) on 75 collectors. Also as routes.csv.

Fix list

The changes that would bring RPKI, the IRR and what's announced into line. Some are deliberate (a route object kept for a backup route, say); the network decides. All 3 are in fix.csv.

Route objects not announced

Route objects with origin AS208636 whose prefix no peer sees AS208636 announce. Many are kept on purpose (backup routes, space announced only in some places).

154.56.248.0/22ARIN, RADBValid

Routes: the 08:00 UTC snapshots of 2026-11-12 from 75 RIPE RIS and RouteViews collectors. RPKI: our rpki-client run before the snapshot. IRR: the day's dumps of the five RIR databases and RADB's mirrors. The LEVEL3 and IDNIC databases publish no dump and aren't read, so route objects only there count as none.
