About this network

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.
