Summary

Beckman Coulter

United States of America · AI-generated

business corporate diagnostics subsidiary

BECKMAN-COULTER-ASN is the autonomous system for Beckman Coulter, Inc.

What it's used for

  • The address space carries internal corporate infrastructure for a biomedical diagnostics manufacturer, evidenced by netnames such as BECKMAN, BECKMAN-ES, and BECKMAN-CH and registrants including Beckman Coulter Spain and Beckman Coulter Eurocenter S.A.
  • The AS announces 23040 IPv4 addresses across 54 prefixes with 34 observed neighbours, a ratio consistent with a large internal corporate estate rather than a transit or access provider.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to BECKMAN COULTER, INC., though some are held by regional subsidiaries like Beckman Coulter Spain and Beckman Coulter Eurocenter S.A., and one prefix is registered to Private Customer.
  • Beckman Coulter has been a subsidiary of Danaher Corporation since 2011.
  • The inventory consists of finely subdivided /22 and /23 blocks within the 134.217.0.0/16 range, reflecting site-by-site segmentation of the corporate network.

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 1,771 prefixes, as published 2026-10-15. 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.
