AS292

AS292 (ESNET-WEST) is a small autonomous system registered to the Energy Sciences Network (ESnet), the U.S. Department of Energy's national research-and-education backbone. As observed by RouteViews at 2026-08-15T02:00 UTC, AS292 originates exactly one IPv4 prefix and zero IPv6 prefixes, with a single neighboring ASN visible in the collector's data: AS293.

ESnet's own site does not distinguish AS292 from AS293 anywhere, and AS-path data carries no directionality, so this entry does not characterize AS293 as an upstream, downstream, or transit provider — only as the one neighboring ASN the RouteViews collector currently sees. The single AS292-specific mention found on an operator domain is a backbone-hop identifier in ESnet's own perfSONAR troubleshooting documentation, on a path into NERSC in Berkeley, California.

ESnet is not a commercial ISP. It is a DOE Office of Science program, stewarded and operated by Lawrence Berkeley National Laboratory, built as a high-performance backbone for scientific research rather than general-purpose traffic. Under the single ESnet brand — not broken out by ASN — the operator reports moving roughly 150 petabytes of data per month and connecting 270-plus research and commercial networks to 17 DOE national laboratories and 28 user facilities.

ESnet publishes a single, network-wide selective peering policy (peering@es.net): a peer needs a publicly assigned ASN, RIR-registered and IRR-documented prefixes exchanged over BGP, RPKI-valid announcements, MANRS/BCP38 compliance, and IPv6 or dual-stack sessions; direct-connect peers need at least a 100G port. The policy is filed once, for ESnet as a whole, not separately for AS292 versus AS293.

No notable public abuse signal was found for AS292 as of a 2026-08-15 check: CleanTalk recorded a 0.00% spam rate, and AS292 was absent from both Spamhaus's ASN-DROP list and ipapi.is's top-1,000 abusive-ASN list. No NANOG mailing-list thread or Reddit discussion specifically names AS292; community references to ESnet's 2011 Cogent de-peering incident and its peering reputation sit at the ESnet/AS293 level, not AS292.

Exposure

As observed by RouteViews at 2026-08-15T02:00 UTC, AS292 originates 1 IPv4 prefix and 0 IPv6 prefixes, with exactly 1 observed BGP neighbor, AS293; adjacency direction (upstream, downstream, or peer) is not determinable from this data.

Do-not-confuse

AS292 and AS293 are both registered to ESnet; RouteViews shows AS293 as AS292's only observed BGP neighbor, but no source here establishes a customer/provider direction between them, and ESnet's operator-reported scale (~150 PB/month, 270+ peered networks) is published network-wide, not broken out by ASN.

no notable public abuse signal found as of a 2026-08-15 check — CleanTalk recorded a 0.00% spam rate (0 spam-active IPs), AS292 was absent from Spamhaus's ASN-DROP list, and AS292 was absent from ipapi.is's top-1,000 abusive-ASN list (list dated 2026-08-10); no NANOG mailing-list thread or Reddit discussion specifically names AS292 — the most relevant archived NANOG discussion, the 2011 Cogent de-peering dispute, discusses ESnet broadly and does not mention AS292 [Confirmed for the abuse-feed checks; Likely for the NANOG/Reddit community read] — https://cleantalk.org/blacklists/as292, https://www.spamhaus.org/drop/asndrop.json, https://ipapi.is/most-abusive-asn.html, https://seclists.org/nanog/2011/Jun/1074

Network & routing

Network type

high-performance, unclassified national research-and-education backbone; not a commercial ISP. ESnet6-generation aggregate bandwidth exceeds 57 Tbps including 2.7 Tbps of trans-Atlantic capacity (network-wide figure, not broken out by ASN)

Size

as observed by RouteViews at 2026-08-15T02:00 UTC, 1 IPv4 prefix and 0 IPv6 prefixes, an address-count estimate of 262,144 across that one prefix; AS rank and customer-cone size Unknown [Confirmed for the RouteViews counts; Unknown for rank/cone] — the RouteViews BGP routing data (CC BY 4.0) AS292

Routing/peering

as observed by RouteViews at 2026-08-15T02:00 UTC, AS292 has exactly 1 neighboring ASN, AS293 — the full observed total, not a capped sample; AS-path data carries no directionality, so this entry does not characterize the adjacency as upstream, downstream, or peer. IXP membership: Unknown [Confirmed for the adjacency count; Unknown for IX presence] — the RouteViews BGP routing data (CC BY 4.0) AS292. ESnet's published peering policy (peering@es.net) is Selective, network-wide: requires a publicly assigned RIR ASN, RIR-registered/IRR-documented prefixes exchanged via BGP, RPKI-valid announcements, MANRS/BCP38 compliance, IPv6 or dual-stack sessions, and a minimum 100G port for direct-connect peers; filed once for ESnet as a whole, not separately for AS292 versus AS293

Notable usage

ESnet-wide (not broken out by ASN) — roughly 150 petabytes of data moved per month, traffic volume growing roughly 10x every four years; serves 17 DOE national laboratories and 28 user facilities, connecting to 270+ research and commercial networks worldwide. The only AS292-specific mention found on an operator domain is a backbone-hop identifier ("ESNET.LINK.1") in ESnet's own perfSONAR troubleshooting documentation, on a traceroute path into NERSC in Berkeley, California — geographically consistent with the "ESNET-WEST" registry name, though ESnet's site does not itself use or explain that name [Confirmed] — https://www.es.net/about/, https://www.es.net/engineering-services/the-network/, https://fasterdata.es.net/performance-testing/perfsonar/perfsonar-success-stories/long-distance-troubleshooting/

Related ASNs

AS293, also registered to ESnet — RouteViews' sole observed BGP neighbor for AS292 as of 2026-08-15T02:00 UTC; ESnet's own site does not itself describe a relationship between the two ASNs, so no customer/provider/primary designation is asserted here [Confirmed for the adjacency; Unknown for any hierarchy between them] — the RouteViews BGP routing data (CC BY 4.0) AS292, https://www.es.net/about/

Analyst note

AS292 (ESNET-WEST) is a small ASN registered to ESnet (DOE/LBNL) that remains live, originating one IPv4 prefix as of a mid-August 2026 RouteViews observation, with AS293 as its only observed BGP neighbor and no assertable direction to that adjacency. ESnet's own site does not distinguish AS292 from AS293 organizationally or in its peering policy. Registry allocation and last-changed dates, RIR, AS rank, customer-cone size, RPKI status, IXP presence, upstream relationships, and a direct abuse/RIR contact are all Unknown. No public abuse signal or NANOG/community incident record was found for AS292 specifically.
