AS396291 NCH Healthcare System
Registry name: NCH-HEALTHCARE-SYSTEM - NCH Healthcare System, Inc., US · PeeringDB
Announced routes
Every prefix a peer of the route collectors sees with origin AS396291, 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 AS396291: ARIN::RS-NCHNAPLES. 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 (AS396291 isn't in the set, or no route object for AS396291 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
Nothing to change: every route is RPKI valid with a route object in an RIR database, and every route object is announced.
Route objects not announced
Every route object with origin AS396291 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.
