Summary

Bausch Health

United States of America · AI-generated

business corporate pharma

BAUSCH-ISTA is the autonomous system for Bausch Health US, LLC.

What it's used for

  • The address space carries internal corporate infrastructure, as indicated by the netname BAUSCH-ISTA and registrant Bausch Health US, LLC.
  • The AS announces 768 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a small, self-contained corporate estate rather than a transit or access provider.

Notable

  • The registrants for both announced prefixes, 74.114.184.0/23 and 74.114.186.0/24, align perfectly with the announcer, Bausch Health US, LLC.
  • The address inventory is compact and finely subdivided into two small blocks, reflecting site-by-site segmentation typical of a large corporation's internal 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
