AS196

AS196 is a legacy autonomous system number registered under ARIN to The Boeing Company, the American multinational aerospace and defense corporation. The ASN is one of the earliest ARIN allocations, with a registry registration date of 1988-05-27, and it remains active today as a single-homed corporate stub network. Unlike a transit provider, AS196 announces routes purely for Boeing's own internal use: it originates 16 IPv4 prefixes totaling roughly 133,376 addresses — dominated by the legacy 130.76.0.0/16 block — and announces no IPv6 prefixes at all. Routing sources agree on its stub character: CAIDA reports a single upstream provider, zero peers, and zero downstream customers, with a customer cone of just the ASN itself. Hurricane Electric and IPinfo identify Level 3 / Lumen (AS3356) as the sole observed upstream. RIS visibility is complete for IPv4 (327/327 peers) and absent for IPv6. The registry record also surfaces the now-defunct Connexion by Boeing in-flight broadband service (2004–2006), historically associated with the 83.210.0.0/16 prefix. On the security side, no notable public abuse signal was found as of June 2026 — AS196 is absent from Spamhaus ASN-DROP and no community blocklist or NANOG abuse thread was located — though two routing-hygiene notes stand out: bgp.he.net flags AS196 as announcing bogons (date/prefix undisclosed), and Boeing publishes no RPKI ROAs (0 valid / 0 invalid), a common gap for legacy enterprise networks. The November 2023 LockBit ransomware incident targeted Boeing the corporation as a victim and is not outbound abuse from this AS.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-19 — not in Spamhaus ASN-DROP (list begins at ASN 245), no community blocklist or NANOG abuse thread located. bgp.he.net flags AS196 as announcing bogons (prefix/date undisclosed — routing hygiene note, Unknown severity). The Nov-2023 LockBit ransomware event targeted Boeing as a victim, not outbound abuse from AS196 [Confirmed for Spamhaus/ransomware; Likely for bogon flag and overall-low posture] — spamhaus.org/drop/asndrop.json, bgp.he.net, cybersecuritydive.com

Network & routing

Network type

corporate enterprise / stub AS; single-homed, provides no transit; internal corporate network only [Confirmed] — ipinfo.io/AS196, CAIDA AS Rank

Size

16 IPv4 prefixes, ~133,376 IPv4 addresses (dominated by 130.76.0.0/16); 0 IPv6 prefixes; customer cone = 1 ASN (itself), 16 prefixes, 133,376 addresses [Confirmed] — RIPEstat routing-status/announced-prefixes, CAIDA AS Rank, bgp.he.net

Routing/peering

stub — 1 upstream provider, 0 peers, 0 customers (CAIDA asnDegree); sole observed upstream Level 3 / Lumen (AS3356); RIS v4 visibility 327/327 (100%), v6 0/323 (0%); no public peering policy and no PeeringDB listing (404 for /asn/196) [Confirmed for stub/upstream/visibility; Likely for "no PeeringDB listing" via 404]

RPKI

no ROAs published — bgp.he.net shows 0 RPKI-valid and 0 RPKI-invalid origins; a routing-security gap typical of legacy enterprise networks, not an abuse signal [Confirmed]

Notable usage

Boeing internal corporate network. The 83.210.0.0/16 prefix is historically associated with Connexion by Boeing (CbB), a defunct Ku-band in-flight broadband service (commercial launch May 2004, discontinued 2006-12-31) [Confirmed] — en.wikipedia.org/wiki/Connexion_by_Boeing, bgp.he.net

ARIN record address 100 N. Riverside, Chicago, IL 60606-1596, US; current corporate HQ has since relocated to Arlington, Virginia [Confirmed for ARIN address; Confirmed for relocation per Wikipedia] — ARIN RDAP autnum/196, en.wikipedia.org/wiki/Boeing

Analyst note

Active single-homed enterprise stub registered to one of the earliest ARIN ASNs (1988). Entity-level RDAP dates (2005-01-14 contact events; 1988-06-13 org event) are decoys; allocated_date is the autnum top-level registration event 1988-05-27.
