Unclassified ARIN
Summary
Lockheed Martin Corporation
business enterprise government
One hostname names a security zone, a project, a service and its instance number.
What it's used for
- A defence and aerospace contractor's network. 256 addresses in a single IPv4 prefix, with two observed BGP neighbours and no IPv6 announced.
Notable
- One sampled address answers as
dmz-proj-semafor-service-10.atl.external.lmco.com, which names a security zone, a project, a role, an instance number and a site in one string. - The whole footprint is
192.35.37.0/24, carrying the netnameGE4and registered to the company. - That netname is two letters of a company absorbed into this one long ago, plus a counter.
- The AS handle pairs the company's initials with the same site code as the hostname.
Interesting
- The hostname is a small map. It tells a reader which zone the host sits in, that the zone faces outward, which project owns it, what it does and that there are others like it. Internal naming conventions are useful precisely because they carry that much, and publishing one in the reverse DNS hands the same convenience to anybody who looks.
- Naming a project in a public record is the part worth flagging for an organisation in this sector, and it costs nothing to strip.
- The netname preserves a corporate ancestor two mergers back, which is the usual fate of these fields.
- Two upstreams and a single small block, with the vast majority of a contractor of this size living on networks that are not routed publicly at all.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-02, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
