AS71

AS71 is a legacy allocation registered under ARIN to HP Inc. (org HPINC-Z, Palo Alto, CA), carrying the modern ARIN ASName "HPINC-AMERICAS." Historically it was "HP-INTERNET-AS / Hewlett-Packard Company" (RFC 1166, 1990). When Hewlett-Packard Company split — effective November 1, 2015, with Hewlett Packard Enterprise spun off and HP Co. renamed HP Inc. — AS71 landed with HP Inc., re-registered in 2016, not with HPE. This matters for triage: bgp.tools displays AS71 as "Hewlett Packard Enterprise," which conflicts with the authoritative ARIN OrgName "HP Inc." — trust ARIN. Contrary to the earlier "dormant" characterization, AS71 is ACTIVE: at the 2026-06-19 capture RIPEstat saw 9 IPv4 prefixes originated (~2,304 addresses, a cluster of legacy 192.56.x /24s such as 192.56.8.0/24, 192.56.10.0/24 and 192.56.15.0/24) plus 2 IPv6 /48s (2620:18d:105::/48 and 2620:18d:107::/48). Visibility is essentially full (IPv4 327/327, IPv6 323/323 RIS peers) and last-seen is today (192.56.15.0/24), with one observed neighbour. The ARIN ASN RegDate is 1986-04-14 (the HPINC-Z org RegDate of 2016-08-22 is the post-split re-registration date, not the original assignment). This is a sibling of AS33 (also HP Inc., historically DEC-WRL). For triage, AS71 is a small but live HP Inc. enterprise origin. No notable public abuse signal was found as of June 2026.

Notable usage

[historical, RFC 1166] AS71 "HP-INTERNET-AS / Hewlett-Packard Company." [current] HP Inc., re-registered 2016 after the Nov 1, 2015 HP split (HPE spun off; HP Co. renamed HP Inc.); actively announcing a small block of legacy 192.56.x space + IPv6 — hp.com

Analyst note

Small but ACTIVE HP Inc. enterprise origin (9 IPv4 + 2 IPv6 prefixes, last-seen today, full RIS-peer visibility). The bgp.tools display "Hewlett Packard Enterprise" conflicts with ARIN's "HP Inc." — trust ARIN.
