Summary

// analyst note
Clean, single-homed HPE enterprise/legacy ASN; sole upstream AS7018 (AT&T). Current WHOIS resolves to HPE; SGI/INTELLIAUTON is historical heritage, not a current registry fact. CAIDA clique_member=true is atypical for a stub and noted as Likely.
// security note
NEUTRAL/DATED: no notable public abuse signal found as of 2026-06-16; not on Spamhaus ASN DROP; no NANOG incident threads located.

About this ASN.

Updated  ·  Confidence: High

AS157 is a low-numbered, legacy Autonomous System Number registered under ARIN to Hewlett Packard Enterprise Company (ARIN OrgId HPE-15), with the registrant address at 1701 E. Mossy Oaks Road, Spring, TX 77389. The ARIN autnum record carries a registration event of 1988-02-05, placing the number among the early ASN allocations, though that registry date reflects the original assignment rather than HPE's tenure. Multiple third-party trackers report that the ASN's earlier name was "INTELLIAUTON" and that it passed through Silicon Graphics International Corp. (SGI) before HPE acquired SGI in November 2016 and the number transferred to HPE; the current RDAP record exposes only the HPE org-level vCard, so the SGI/INTELLIAUTON lineage is best treated as third-party heritage rather than a current registry fact. In routing terms AS157 is a textbook single-homed stub: it originates just two IPv4 prefixes — 192.48.180.0/22 and 192.48.184.0/21, about 3,072 addresses — announces no IPv6, and has a single observed upstream/peer in AS7018 (AT&T). RIPEstat shows full IPv4 visibility (327/327 RIS peers) and a routing history reaching back to August 2000. The one operational gap worth flagging is RPKI/IRR hygiene: neither announced prefix has a valid ROA, and both show IRR parent-route origin mismatches. No notable public abuse signal was found as of June 2026 — it reads as a clean, corporate-held enterprise/legacy ASN.

Network & routing

Network type
enterprise/corporate infrastructure, single-homed stub AS (no transit provided) [Confirmed] — bgp.tools/as/157, ipinfo.io/AS157
Size
small — 2 IPv4 prefixes (192.48.180.0/22 + 192.48.184.0/21 ≈ 3,072 addresses), 0 IPv6 [Confirmed] — stat.ripe.net (routing-status/announced-prefixes), bgp.he.net/AS157, bgp.tools/as/157
Routing/peering
single observed upstream and BGP peer AS7018 (AT&T Enterprises, LLC); observed_neighbours = 1; IPv4 visibility 327/327 RIS peers, IPv6 0/319 [Confirmed] — stat.ripe.net/data/routing-status, bgp.he.net/AS157, bgp.tools/as/157
Routing history
first seen 2000-08-18 (prefix 192.82.208.0/24), last seen 2026-06-15 [Confirmed] — stat.ripe.net/data/routing-status
RPKI/IRR
no valid ROAs; both announced prefixes show IRR parent-route origin mismatches (operational hygiene gap, not an abuse event) [Confirmed] — bgp.he.net/AS157
CAIDA
AS Rank 24,320; is_ixp = null; geo ≈ Spring, TX (lat 30.05 / lon -95.53); clique_member flagged true [Likely — clique flag atypical for a small stub; sourced verbatim from CAIDA] — api.caida.org/as-rank/v1/asns/157
Peering policy / IX presence
no public peering policy or PeeringDB entry found (peeringdb.com/net/157 → 404); no Internet Exchange membership observed [Likely] — peeringdb.com, bgp.he.net/AS157, bgp.tools/as/157
Notable usage
HPE corporate/enterprise network carrying a small footprint relative to HPE's overall address holdings; reportedly held earlier as "INTELLIAUTON" and via SGI before HPE's ~$275M SGI acquisition (Nov 2016) [Likely — third-party trackers; not in current RDAP] — bgpview.io/asn/157, en.wikipedia.org/wiki/Silicon_Graphics_International
Related ASNs
AS7018 (AT&T, sole observed upstream/peer) [Confirmed]
Analyst note
Encountered as a clean, single-homed HPE enterprise/legacy ASN; current WHOIS resolves to HPE, with SGI/INTELLIAUTON as historical heritage. Sole material gap is missing RPKI ROAs on both prefixes.
