Announced routes

Every prefix a peer of the route collectors sees with origin AS2848, 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.

AS-SET

PeeringDB's irr_as_set for AS2848: RIPE::AS-MSU. Expanded from the day's IRR dumps the way bgpq4 does against whois.radb.net: a name with a database is read from that database only, one without from the first database in RADB's order. "Not covered" = this network's own routes that a filter built from the set would leave out (AS2848 isn't in the set, or no route object for AS2848 covers the route; more-specifics of a route object are accepted down to /24 and /48, as with bgpq4 -A -R 24 / -R 48). Customers' routes aren't counted: the collectors show each route's origin, not which network it came through.

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 2 are in fix.csv.

ROA: maxLength188.44.63.0/24ROA 188.44.32.0/19 AS2848 has maxLength 19; the route is a /24. Raise the maxLength, or add a ROA for 188.44.63.0/24.17 of 673
Route object: none188.44.63.0/24No route object for it. A route object for 188.44.32.0/19 with origin AS2848 covers it (filters allowing more-specifics accept it). Add a route object with origin AS2848 in the RIR database for the space.17 of 673

Route objects not announced

Every route object with origin AS2848 is announced.

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.
