Autonomous system detail

AS210

Announced

Operated by WEST-NET-WEST - Utah Education Network.

Summary

// analyst note
Active, well-routed regional education backbone, clean reputation. Allocation date 1996-10-01 is the autnum top-level ARIN registration event; the 1993-10-13 org-registrant date (UEN-4) is a decoy and not used. AS rank 2999 (clique member), customer cone 8 ASNs / 78 prefixes / 2,478,336 addresses, and asnDegree 14 total (6 providers / 7 customers / 1 peer) from CAIDA AS-Rank canonical fetch.
// security note
NEUTRAL/DATED: no notable public abuse signal as of 2026-06-19; not on Spamhaus DROP, CleanTalk, FraudGuard, Emerging Threats, or FireHOL.

About this ASN.

Updated  ·  Confidence: High

AS210 is an active autonomous system registered under ARIN to the Utah Education Network (UEN), the statewide research-and-education (R&E) broadband network that links Utah's K-12 schools, higher-education institutions, public libraries, and telehealth sites. The operating organization is today the Utah Education and Telehealth Network (UETN), created in 2014 when Utah HB92 merged UEN with the Utah Telehealth Network; the network still runs publicly under the UEN brand and the ARIN handle WEST-NET-WEST. The ASN is firmly active and well-routed: RIPEstat shows roughly 31 IPv4 prefixes and a single IPv6 prefix (2001:1948::/32) announced, covering on the order of 1.4 million IPv4 addresses, with full RIS visibility (327/327 peers on v4, ~320/323 on v6). Operationally the network is headquartered at the Eccles Broadcast Center in Salt Lake City and reports 300–500 Gbps of (predominantly inbound) traffic serving 2,000-plus institutions across urban and rural Utah. UEN runs an open peering policy (no contract, no ratio requirement; IRR as-set RADB::AS210:AS-CONE) and participates at the SLIX (Salt Lake City) and SUPRnet (Southern Utah) exchanges. Security posture is clean: no listing on Spamhaus DROP, CleanTalk, FraudGuard, FireHOL, or other reviewed feeds as of June 2026. The only adverse archive reference is a July 2010 NANOG BGP-update report that placed AS210 among the top-20 most unstable origin ASes for one week — a dated, non-security event with no comparable follow-on.

Operator
Utah Education Network (UEN), operated by the Utah Education and Telehealth Network (UETN) (ARIN handle WEST-NET-WEST; registrant org UEN-4, Salt Lake City, UT) [Confirmed] — ARIN RDAP, uetn.org/about/history.php
Country / RIR
US, ARIN [Confirmed] — ARIN RDAP, RIPEstat as-overview (authoritative_rir: arin)
Allocated
1996-10-01 (ARIN RDAP autnum top-level registration event — a first-party RIR fact, NOT an IEEE date); last changed 2025-06-24 [Confirmed] — ARIN RDAP autnum top-level events. Note: the UEN-4 org registrant record carries a 1993-10-13 date — a decoy, not the autnum allocation.
Org status
state-chartered R&E network entity under the University of Utah / Utah System of Higher Education umbrella; ARIN registration active [Confirmed] — ARIN RDAP, peeringdb.com/asn/210
Contacts
noc@uen.org and abuse@uen.org, +1-801-585-7440; Eccles Broadcast Center, 101 Wasatch Drive, Salt Lake City, UT 84112 [Confirmed] — ARIN RDAP

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal as of 2026-06-19 — not on Spamhaus DROP/ASN-DROP, CleanTalk, FraudGuard, Emerging Threats, or FireHOL [Likely — several feeds returned 403/404 on query]. An HE.NET bogon flag is contradicted by BigDataCloud (0 bogon prefixes) and appears stale. A July 2010 NANOG report listed AS210 6th among unstable origin ASes (~19,720 updates that week) — dated, non-security [Confirmed for the 2010 report]

Network & routing

Network type
educational / research — statewide broadband network serving Utah K-12, higher education, public libraries, and telehealth/healthcare [Confirmed] — peeringdb.com/asn/210, uetn.org/about/history.php
Size
~31 IPv4 prefixes (~1,424,128 addresses) and 1 IPv6 prefix (2001:1948::/32); full routing visibility (327/327 v4 RIS peers, ~320/323 v6); first seen in routing 2000-08-18; ~14 observed BGP neighbours [Confirmed] — RIPEstat routing-status / announced-prefixes (2026-06)
Routing/peering
open peering policy (no contract, no ratio, single location ok); IRR as-set RADB::AS210:AS-CONE; present at SLIX (Salt Lake City, 100G) and SUPRnet (Southern Utah, 10G), both with route servers; IPv4 + IPv6 unicast, no multicast [Confirmed] — peeringdb.com/asn/210
Upstreams / AS rank / customer cone
AS rank 2999 (clique member); customer cone 8 ASNs / 78 prefixes / 2,478,336 addresses; asnDegree 14 total (6 providers / 7 customers / 1 peer) [Confirmed] — CAIDA AS-Rank (caida.org/catalog/datasets/as-rank/)
RPKI
Unknown / partial — prefix-level rpki-validation was skipped (no prefix supplied to canonical fetch); third-party views (bgp.tools) suggest ROA coverage on roughly half the IPv4 prefixes but this is not first-party verified [Unknown for full posture]
Notable usage
connects 2,000+ K-12 schools, higher-ed institutions, public libraries, and telehealth sites across Utah; 300–500 Gbps predominantly inbound; operates the Eccles Broadcast Center; received CARES Act pandemic funding for network upgrades [Confirmed for scale/role via PeeringDB + uetn.org; Likely for funding figure]
Legal name history
UETN was created in 2014 via Utah HB92, merging UEN with the Utah Telehealth Network; statutory authority Utah Code 53B-17-101 et seq.; network still branded UEN [Confirmed] — uetn.org/about/history.php, le.utah.gov interim doc
Nearby ecosystem incidents (NOT AS210 infrastructure)
PowerSchool breach (Dec 2024), Granite School District ransomware (2024), Instructure/Canvas attack (May 2026) affected Utah education institutions via SaaS vendors, not AS210's routing or network [Confirmed these are SaaS/member incidents, not ASN-attributable]
Analyst note
Active, well-routed regional education backbone with a clean reputation. Watch points are the decoy 1993 org-registrant date (autnum allocation is 1996-10-01) and the stale HE.NET bogon flag.
