AS890

AS890 is an active-registry, currently-dormant autonomous system that ARIN allocated on 2022-06-07 to Hermiston School District 8R, a public K-12 school district in Hermiston, Oregon — not a commercial ISP or transit provider. As of an August 2026 routing check, it announces zero IPv4 and zero IPv6 prefixes, with zero BGP peers and zero upstreams visible anywhere.

The ARIN RDAP autnum record lists the object status as Active, but that reflects registry housekeeping, not live routing, and should not be conflated with the ASN actually appearing in the global BGP table. CAIDA's AS Rank (79,459) confirms the ASN is absent from its measured topology and is not a route-view clique member; its customer cone is a singleton of itself, with zero prefixes and zero addresses.

ARIN's autnum name, EXTERNAL-ASN-HSD-01, together with the registrant being a school district IT department, points to an enterprise/institutional ASN meant for the district's own external BGP multihoming rather than one that peers with or transits traffic for third parties. This is an inference from naming and registrant type, not a classification the operator has published anywhere; no PeeringDB network record exists for AS890.

bgp.he.net lists an IRR route/as-set object for AS890 maintained under MAINT-CHTR-WD, a Charter Communications-associated maintainer handle, with an object description reading CHTR-HERMISTON SCHOOL DISTRICT-Northwest. That is consistent with Charter (operating as Spectrum Enterprise) acting as the district's likely upstream provider and maintaining routing-registry objects on its behalf — it is not evidence that Charter operates or holds AS890; ARIN RDAP is unambiguous that the district is the sole registrant.

Operator

Hermiston School District 8R (ARIN org handle UCSDR; autnum EXTERNAL-ASN-HSD-01), Hermiston, Oregon [Confirmed] — https://rdap.arin.net/registry/autnum/890

Country / RIR

US, ARIN [Confirmed] — https://rdap.arin.net/registry/autnum/890

Allocated

2022-06-07 (ARIN RDAP autnum top-level registration event; last-changed event carries the same date, no subsequent change recorded) [Confirmed] — https://rdap.arin.net/registry/autnum/890

Org status

ARIN RDAP status Active; registrant is a public K-12 school district, not a commercial network operator or ISP [Confirmed] — https://rdap.arin.net/registry/autnum/890

Contacts

technicalstaff@hermistonsd.org; +1-541-667-6000; IT Department Staff (ARIN handle IDS12-ARIN, status Validated); 305 SW 11th St, Hermiston, OR 97838 [Confirmed] — https://rdap.arin.net/registry/autnum/890

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of an August 2026 search across Spamhaus DROP context, generic bad-ASN blocklist compilations, and NANOG archives; URLhaus's per-ASN page was bot-gated and unreadable and no AbuseIPDB page was found, so those two remain Unknown

Network & routing

Network type

Unknown/not officially self-described; naming (EXTERNAL-ASN-HSD-01) and registrant type suggest an enterprise/institutional multihoming ASN rather than transit or eyeball-ISP [Likely] — https://rdap.arin.net/registry/autnum/890

Size

dormant — 0 IPv4 prefixes / 0 addresses and 0 IPv6 prefixes; CAIDA customer cone = 1 ASN (itself), 0 prefixes, 0 addresses; CAIDA AS rank 79,459, not seen in topology, not a clique member [Confirmed] — https://stat.ripe.net/AS890, https://api.asrank.caida.org/v2/restful/asns/890, https://bgp.he.net/AS890, https://bgp.tools/as/890

Routing/peering

NOT announced — 0/327 RIS peers seeing v4, 0/321 seeing v6; CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers in any source; no PeeringDB network record exists (404 on both the web page and API) [Confirmed] — https://api.asrank.caida.org/v2/restful/asns/890, https://www.peeringdb.com/asn/890, https://www.peeringdb.com/api/net?asn=890

RPKI

not assessable — AS890 announces no prefixes, so RIPEstat's RPKI-validation check found none to evaluate [Confirmed] — https://stat.ripe.net/AS890

Notable usage

no live routing usage; ARIN RDAP registry status is Active but this is a registry-record state, not an observed announcement — third-party BGP tools show 0 originated prefixes as of an August 2026 snapshot [Confirmed] — https://bgp.he.net/AS890, https://rdap.arin.net/registry/autnum/890

Related ASNs

none confirmed; bgp.he.net's IRR data shows a route/as-set object maintained under a Charter Communications-associated handle (MAINT-CHTR-WD, AS-CHTR-BB), consistent with Charter as the district's likely upstream provider maintaining registry objects on its behalf — this is not a registrant or operator relationship [Unknown, flagged as unverified IRR artifact] — https://bgp.he.net/AS890, https://bgp.he.net/irr/as-set/AS-CHTR-BB

Analyst note

encountered as a dormant, currently-unannounced ASN registered to a US public school district's IT department; ARIN registry status is Active but no routing activity is observed in any of four independent BGP sources, and no PeeringDB or published peering policy exists. — https://rdap.arin.net/registry/autnum/890, https://stat.ripe.net/AS890
