AS193

AS193 is a low-numbered, early-registered Autonomous System Number held under ARIN by Lockheed Martin Corporation, the publicly traded U.S. aerospace and defense contractor (NYSE: LMT). The ARIN RDAP autnum record carries a top-level registration event of 1996-08-26 and a last-changed event of 2023-11-20, with status active; the registrant vCard resolves to Lockheed Martin Corporation, and the network contact on record is lm-nic@lmco.com at 1401 Del Norte St., Denver, CO 80221. A notable quirk is the AS name itself: the handle is named FORD-ASN, a label that predates the current Lockheed Martin registrant and reflects an earlier assignment era — the name should not be read as identifying the present holder. The key triage point for AS193 is that it is dormant today. Every routing source consulted agrees it announces zero IPv4 and zero IPv6 prefixes: RIPEstat reports it as not announced with 0 of 327 v4 RIS peers and 0 of 323 v6 RIS peers seeing it, CAIDA AS Rank has never seen it active (seen=false, AS rank 79,459, all degree values 0, customer cone a singleton of itself), and bgp.he.net corroborates 0 prefixes and 0 peers. RPKI posture is therefore not assessable — with no active originations there are no ROAs to validate. Lockheed Martin's operationally active routing appears to run under a different ASN (commonly cited as AS6075), not AS193. No notable public abuse signal was found as of 2026-06-18 — not in Spamhaus ASN-DROP, AbuseIPDB, CleanTalk, or NANOG archives — consistent with a clean, dormant enterprise ASN; the organisation is a recurring TARGET of nation-state and hacktivist campaigns (including an unconfirmed March 2026 data-exfiltration claim by a pro-Iranian group), but none of those incidents implicate AS193's IP space as a source of malicious traffic.

Operator

Lockheed Martin Corporation (ARIN registrant; network contact lm-nic@lmco.com; registrant address 1401 Del Norte St., Denver, CO 80221, US) [Confirmed] — ARIN RDAP (https://rdap.arin.net/registry/autnum/193), ipinfo.io/AS193

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP (https://rdap.arin.net/registry/autnum/193)

Allocated

1996-08-26 (ARIN autnum top-level registration event, NOT an IEEE date — IEEE publishes no ASN registration dates); last changed 2023-11-20 [Confirmed] — ARIN RDAP autnum top-level events (https://rdap.arin.net/registry/autnum/193)

AS name

FORD-ASN — a legacy label that predates the current Lockheed Martin registrant; reflects an earlier assignment era and should not be read as the present holder [Confirmed] — ARIN RDAP (https://rdap.arin.net/registry/autnum/193)

Org status

active; Lockheed Martin Corporation is publicly traded (NYSE: LMT), an aerospace/defense/global-security company; corporate HQ 6801 Rockledge Drive, Bethesda, MD; ~121,000 employees [Confirmed] — https://www.lockheedmartin.com/en-us/who-we-are.html

Contacts

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-18 — not on Spamhaus ASN-DROP, AbuseIPDB, CleanTalk, or NANOG archives; closed enterprise network. Lockheed Martin is a recurring TARGET of nation-state/hacktivist campaigns (e.g. unconfirmed March 2026 pro-Iranian exfiltration claim; 2011 RSA SecurID-linked VPN intrusion that prompted Lockheed's Cyber Kill Chain framework), but none implicate AS193's IP space as an abuse source

Network & routing

Network type

enterprise / corporate internal network (defense contractor); AS193 is legacy/inactive — Lockheed Martin's active routing is commonly attributed to AS6075, not AS193 [Confirmed] — ipinfo.io/AS193, bgp.he.net/AS193

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status / CAIDA AS Rank / bgp.he.net (2026-06)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/327 v4, 0/323 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible in any source; no public peering policy and no PeeringDB record (404) [Confirmed for not-announced; Unknown for any policy] — RIPEstat routing-status (https://stat.ripe.net/data/routing-status/data.json?resource=AS193), bgp.he.net/AS193

RPKI

not assessable — AS193 announces no prefixes, so there are no ROAs to validate; bgp.he.net shows 0 RPKI-valid and 0 RPKI-invalid origins [Confirmed] — bgp.he.net/AS193

Notable usage

legacy/inactive ASN registered to Lockheed Martin Corporation, a U.S. aerospace and defense contractor (Fortune 500). No prefixes announced; the AS appears retired for active routing while remaining registered

Analyst note

Encountered as a dormant legacy ASN whose WHOIS resolves to Lockheed Martin Corporation under the legacy handle FORD-ASN. Three independent routing sources (RIPEstat, CAIDA, bgp.he.net) agree on zero announcements / zero peers / zero cone; bgp.tools was unavailable (HTTP 500) at query time. The nested LHMC-Z org/contact event dates (2010-06-29 registration, 2011-09-24 last changed) are record-maintenance dates and were correctly ignored in favour of the autnum top-level 1996-08-26 registration. Clean, inactive ASN.
