AS91 Rensselaer Polytechnic Institute
Registry name: RPI-AS - Rensselaer Polytechnic Institute, US · PeeringDB
Announced routes
Every prefix a peer of the route collectors sees with origin AS91, 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 12 are in fix.csv.

| Route object: none | 2620:0:bf0::/48 | No route object for it. Add a route object with origin AS91 in the RIR database for the space. |

Route objects not announced
Route objects with origin AS91 whose prefix no peer sees AS91 announce. Many are kept on purpose (backup routes, space announced only in some places).

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.
