AS125

AS125 is a live, fully-routed autonomous system registered to Honeywell International, Inc. that announced 30 IPv4 prefixes and no IPv6 space in the current RouteViews snapshot (2026-08-14) — an actively used enterprise network, not a dormant or legacy-inactive ASN. Those prefixes carry an estimated 11,008 addresses, and RouteViews observed 8 distinct neighboring ASNs adjacent to AS125 in the same snapshot.

Those 8 neighbors — AS3356, AS4755, AS6461, AS6939, AS7473, AS11247, AS22773, and AS198949 — are bare BGP adjacencies observed in that snapshot, with no confirmed transit direction. Adjacency alone cannot show which are upstream providers, downstream customers, or settlement-free peers, so none is labeled as such, and no relationship between AS125 and any of the eight — including AS11247 — is asserted.

RPKI validation has not been performed for AS125's announced prefixes as of an August 2026 search, so origin-validation posture is unestablished — an absence of checking, not a finding of clean or complete ROA coverage. AS125's global traffic rank and customer-cone size are Unknown.

Honeywell has undergone major restructuring since 2025: it spun off Solstice Advanced Materials on 2025-10-30 and Honeywell Aerospace on 2026-06-29, then rebranded its remaining automation business as "Honeywell Technologies" (still trading as Nasdaq: HON) effective the same date. No source ties AS125 specifically to any one of the resulting entities, and Honeywell's own site publishes no peering policy or network-operations page — consistent with an end-user enterprise network rather than a transit provider.

Exposure

AS125 is fully routed — 30 IPv4 prefixes, 0 IPv6 — with 8 observed neighbor adjacencies in the current RouteViews snapshot; its exposure surface is whatever Honeywell operates behind those prefixes, not the ASN registration itself.

RPKI

Unavailable / not checked as of an August 2026 search — no ROA-validation result is on record for AS125's announced prefixes; treat origin-validation posture as unestablished, not as confirmed-clean.

Transit relationships

Unknown — RouteViews shows 8 neighbor adjacencies (AS3356, AS4755, AS6461, AS6939, AS7473, AS11247, AS22773, AS198949) in the current snapshot, but plain BGP adjacency does not indicate provider, customer, or peer roles, so none is asserted.

Abuse contact

Unknown as of an August 2026 search — no network abuse-desk address is on record for AS125.

Operator

Honeywell International, Inc. (Nasdaq: HON), a multinational industrial-automation and technology conglomerate; current public brand "Honeywell Technologies" as of 2026-06-29. AS name HI-NET-AS is the registry short-name carried from the prior record.

Country / RIR

US, ARIN [Likely] — inferred from Honeywell being a US-headquartered public company (honeywell.com); the RIR assignment itself is not independently confirmed against a registry source

Allocated / last updated

Unknown. [Unknown]

Org status

active; public company (Nasdaq: HON). Completed two spin-offs in 2025-2026 — Solstice Advanced Materials (2025-10-30) and Honeywell Aerospace (2026-06-29) — and rebranded its remaining automation business as "Honeywell Technologies" effective 2026-06-29. No source confirms which post-spin-off entity now holds AS125 [Confirmed for the restructuring; Unknown for AS125's entity assignment] — honeywell.com/us/en/press/2025/10/honeywell-announces-updated-business-segment-structure-ahead-of-aerospace-spin-off, prnewswire.com/news-releases/honeywell-unveils-new-brands-effective-post-spin-off-honeywell-technologies-and-honeywell-aerospace-302786578.html

Contacts

Unknown — no abuse-desk or NOC address is confirmed for AS125 from an available source [Unknown]

Security/abuse context (NEUTRAL, DATED)

no notable public abuse or threat-feed listing found for AS125 as of an August 2026 search (checked against the Spamhaus Blocklist, ThreatFox/abuse.ch, Cisco Talos reputation data, and CINS Army/Emerging Threats compromised-IP lists); no NANOG mailing-list thread names the ASN in the SecLists.org or lists.nanog.org archives. Abuse contact: Unknown [Confirmed for the negative search results; Unknown for abuse contact] — spamhaus.org/blocklists/spamhaus-blocklist, threatfox.abuse.ch, talosintelligence.com/reputation, cinsarmy.com/list-download, seclists.org/nanog, lists.nanog.org/archives/list/nanog@lists.nanog.org

Network & routing

Network type

enterprise / end-user corporate network, not a network operator — Honeywell describes itself as an industrial-automation and technology company (Building Automation, Process Automation and Technology, Industrial Automation segments); no peering/ASN/BGP content found on its own site

[Likely] — honeywell.com/us/en/company/about-us

Size

30 IPv4 prefixes, ~11,008 addresses, 0 IPv6 prefixes, as observed by RouteViews in the current snapshot [Confirmed] — the RouteViews BGP routing data (CC BY 4.0) 125

Routing/peering

8 distinct neighboring ASNs observed by RouteViews in the current snapshot — AS3356, AS4755, AS6461, AS6939, AS7473, AS11247, AS22773, AS198949 — the complete adjacency list, not a sample; BGP adjacency alone establishes no transit direction, so none is labeled provider, customer, or peer [Confirmed for the adjacency list; Unknown for role/direction] — the RouteViews BGP routing data (CC BY 4.0) 125

Peering policy

not publicly published — a site-restricted search of honeywell.com and investor.honeywell.com for "peering", "autonomous system", "ASN", and "BGP" returned no networking-infrastructure content [Confirmed absent] — honeywell.com/us/en/company/about-us

RPKI

not checked as of an August 2026 search — no ROA-validation result is on record for AS125's announced prefixes, so origin-validation posture is unestablished; this is an absence of checking, not a finding of clean or missing coverage [Unknown]

AS rank / customer-cone size

Unknown. [Unknown]

Notable usage

Honeywell's own material describes company-wide operating scale — "6.4M+ assets", "32,000+ Customers", "324,000+ Sites" connected via the Honeywell Forge platform, figures current on the company's About page as of March 2026. This describes the parent company's overall business, not AS125 specifically; no source names the ASN or describes what traffic it carries [Confirmed for the company-scale figures; Unknown for AS125-specific usage] — honeywell.com/us/en/company/about-us

Related ASNs

Unknown — no source independently confirms a relationship between AS125 and any other ASN; AS11247 appears only as one of the 8 bare RouteViews-observed adjacencies (see Routing/peering above), with no ownership or transit link established [Unknown]

Analyst note

a live, fully-routed enterprise ASN for Honeywell International, Inc. — 30 IPv4 prefixes, 0 IPv6, 8 neighbor adjacencies, all as observed by RouteViews, with no transit direction established for any of them. RPKI status, AS rank, customer-cone size, allocation/last-updated dates, related ASNs, and abuse contact are all Unknown. Honeywell completed two 2025-2026 spin-offs and rebranded as "Honeywell Technologies" in June 2026; no source ties AS125 to a specific post-spin-off entity
