Summary

B. Braun Melsungen AG

Germany · AI-generated

business medical corporate

BBRAUN_AS is operated by B. Braun Melsungen AG.

What it's used for

  • The address space carries internal corporate infrastructure, as indicated by netnames DE-BBRAUN-960624, DE-BBRAUN-980202, and BRAUN registered to B. Braun Melsungen AG and Aesculap AG.
  • The network announces 33024 IPv4 addresses across 3 prefixes with only 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic consists of office workers, manufacturing sites, and internal systems for a global medical technology and pharmaceutical contract manufacturing company.

Notable

  • Registrants align with the announcer, listing B. Braun Melsungen AG for the two largest prefixes and Aesculap AG for the smallest prefix, both under the same network operator.
  • Aesculap AG is a subsidiary of B. Braun Melsungen AG, explaining the shared network operation and distinct registrant name for the 194.45.142.0/24 block.
  • The inventory is finely subdivided into three distinct prefixes, reflecting site-by-site segmentation typical of a large industrial corporation.

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 1,852 prefixes, as published 2026-11-08. 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.
