Summary

Siemens Healthineers

Germany · AI-generated

business medical corporate germany

VMS-AS is held by Siemens Healthineers AG.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames such as VARIAN-MEDICAL-SYSTEMS-NETWORK and registrants listed as Varian Medical Systems; Varian Associates Inc.
  • The AS announces 14,848 IPv4 addresses across 23 prefixes with only 1 observed neighbour, indicating a single-site or internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate communications, medical device management, and administrative endpoints for Siemens Healthineers and its subsidiary Varian.

Notable

  • Registrants for the largest prefixes are listed as Varian Medical Systems; Varian Associates Inc, which aligns with the announcer Siemens Healthineers AG given Varian's status as a subsidiary.
  • Varian Medical Systems was acquired by Siemens Healthineers, explaining the retention of legacy netnames and registrant data within the current AS.
  • The inventory is finely subdivided into 23 prefixes, mostly /23 and /24 blocks, consistent with site-by-site segmentation of a large corporate network.

Reputation

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.
