Summary

Siemens

United States of America · AI-generated

business corporate industrial

SIEMENS-PLM is the autonomous system for Siemens Corporation.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the consistent netname SIEMENS-AG across all registrant entries.
  • The AS announces 4352 IPv4 addresses across 12 prefixes and 2 IPv6 prefixes, maintaining 10 observed neighbours. This ratio of a finely subdivided address inventory against a moderate number of peers indicates an internal corporate estate with site-by-site segmentation rather than a transit or access network.

Notable

  • All registrants align with the announcer, with every prefix registered to Siemens Corporation under the netname SIEMENS-AG.
  • The address inventory is fragmented into numerous /24 and /23 blocks, primarily within the 134.244.0.0/16 and 146.122.0.0/16 ranges, reflecting a distributed internal network structure.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 436 networks and 1,771 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.
