Summary

United States of America · AI-generated

business rail manufacturing corporate

GREENBRIER-AS is the autonomous system for The Greenbrier Companies, Inc.

What it's used for

  • The space carries corporate infrastructure for a global railcar manufacturer, as indicated by the netname GREENBRIER-1 and registrant THE GREENBRIER COMPANIES, INC.
  • The AS announces 512 IPv4 addresses within a single prefix (192.161.38.0/23) and has 1 observed neighbour, a ratio consistent with an internal corporate estate rather than a transit or access network.

Notable

  • The RDAP registrant matches the AS holder, confirming the space is owned and operated by The Greenbrier Companies.
  • The address inventory consists of a single /23 block, representing a small, self-contained network footprint typical of a large enterprise's internal connectivity.

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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
