Summary
Caterpillar
enterprise business infrastructure
One manufacturer's network holding address space from three regional registries at once.
What it's used for
- A global manufacturer's corporate network. 135,936 addresses across 26 IPv4 prefixes plus three IPv6 prefixes, with five observed BGP neighbours.
Notable
- The bulk is
137.230.0.0/16under the netnameCATNET, plus165.26.0.0/17and eight smaller pieces of the same range, all under the netnameCAT. 103.98.174.0/23is registered through a different regional registry asCATERPILLAR-US, with an incident-response object namedIRT-CATERPILLAR-AP.192.189.128.0/22uses the netnameNET192, registered toVarious Registries (Maintained by ARIN).- The announcement also includes
203.9.78.0/23,185.128.184.0/24,185.128.186.0/24,12.2.142.0/24and12.15.28.0/24. - The IPv6 side is
2407:2d00::/32plus two/44s of2620:162. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Prefixes from three regional registries in one announcement is what a company with offices on three continents ends up holding. Each region's space was requested locally, years apart, and the routing pulled it all back under one AS number.
- The
12.2and12.15blocks are single/24s carved out of a carrier's range. A customer announcing provider space under its own AS number is keeping the addresses through a change of circuit, which is worth the paperwork only when renumbering would be worse. NET192names a block whose custodian is the registry itself, a marker of registration old enough to predate the current allocation process.

Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
5 upstream, 0 downstream and 9 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
