Summary

Lockheed Martin Corporation

United States · AI-generated

enterprise legacy

LM-CORP is the main autonomous system of Lockheed Martin Corporation, the American aerospace and defence contractor.

What it's used for

  • Corporate connectivity across Lockheed Martin's sites: engineering, manufacturing, business systems and the company's internet-facing services.
  • It originates a large, heavily deaggregated footprint — well over a hundred prefixes drawn from several distinct blocks — which is what a multi-site industrial network with decades of accreted addressing looks like.

Notable

  • This is a corporate network, not a government one: Lockheed Martin is a private company, and the space here is its own enterprise addressing rather than a military network.
  • Its address blocks carry site-specific netnames — for example 137.32.0.0/16 is registered as LFWC-NET, the legacy Lockheed Fort Worth Company block — a fossil record of the mergers that formed the modern company.

Interesting

  • ARIN dates the AS number to November 1995, in the same sequential run as its neighbours. The -Z suffix on the registrant org handle is an ARIN legacy-cleanup artifact, not evidence of a reassignment.
  • Lockheed Martin was formed in 1995 by the merger of Lockheed and Martin Marietta — the same year this number was issued.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
